Conductance,Susceptance,Admittance

admittance of a capacitor

For parallel circuits:

Does a inductor have conductance?

Does a inductor have Susceptance?

Does a inductor have Admittance?

Does a Capacitor have conductance?

Does a Capacitor have Susceptance?

Does a Capacitor have Admittance?

Why is conductance,susceptance,admittance only for parrallel circuit and not
for series circuits ?

Is conductance,susceptance,admittance frequency based?

What does conductance,susceptance,admittance do really?

what is admittance

Grab a book or read something like:

what is susceptance

Admittance:
Admittance Y is the reciprocal of impedance. It is also a complex quantity: real part is called conductance ( C ) and the imaginary part is called susceptance ( B ).
The unit of admittance is Siemens (S)

Y = G + jB
Where, Y is admittance; G represents conductance and B susceptance.


This is all it said in that hyperlink i still don't know the answers to my question
from this

admittance susceptance

Sorry, I thought that you just have confusion with terms.

how to calculate admittance?

Conductance, susceptance, and admittance are sometimes called the "evil twins" of resistance, reactance, and impedance,


capacitive susceptance (BC) and inductive susceptance (BL).

Take the reciprocal- Why is that to take the reciprocal?

Whats the difference between Conductance, susceptance, and admittance VS
resistance, reactance, and impedance?

susceptance admittance

reciprocal = pair of fractions whose product is one.

Admittance = 1/Impedance
Conductance = 1/Resistance
and so on

how to calculate admittance

Thanks for help alot

Do they mean the same thing ?

My book says its the INVERSE what does that mean the inverse?

admittance of capacitor

(1/x) is the inverse of (x). ... for x ≠0...
Which is your native language?

admittance,conductance,susceptance(definition)

Why do they want the inverse is it because the components are in parallel and
not series? why the inverse? i don't get why they use the inverse?

how to calcucate susceptance value

I think is just a matter of equation simplicity. It is not an independent concept.
You may ask Flatulent, he usually comes with good answers to that type of questions.

Best Regards!

Let start from resistor:

Normally everybody know that the value of resistor is in resistance. It is look like how much it resist to current flow through. In other way we can also measure in terms of how much it help to current flow. The blue term we called conductance.

In series circuit it is easy to use resistance to calculate (like V, I , Total R), that why we normally used resistance. But in parallel circuits (I thought you might see how difficult to calculate R total), it is more easier to calculate if we use conductance.

The relationship is as you mention R=1/G. Why reciprocal? Because they are in opposite meaning (definition).

susceptance

Thanks for help


How is this conductance,susceptance,admittance used and measured for DC?

How is this conductance,susceptance,admittance used and measured for AC?

In dc there is no reactance, mean no susceptance. It has pure resistance (or conductance). In dc capacitor is look like open circuit and inductor is look like short circuit.
Reactance (susceptance) is depend on the frequency, for dc the frequency is 0. that's why no reactance. Even your circuit include L and C, it has no reactance in DC.
capacitor reactance Xc=1/(2 pi f c);
capacitor susceptance Bc = 1/Xc;
Inductor reactance XL=2 pi f L;
inductor susceptance BL = 1/XL;

But in AC, it may combine all together and from complex number. Resistance (conductance) provide real parts and capacitor or inductor reactance (susceptance) provide imaginary parts. look like

Z(impedance)= R(resistance) + jX(reactance)

Y(admittance)=G(conductance)+jB (susceptance)

Even in AC if your circuit has only resistor, no L or C,
Z has only real parts or we can also say that (Y has only real parts ).

admittance conductance and susceptance

Thanks for the help alot for the information

So does every AC circuit have both of these going on
for a AC series circuit and AC parallel circuits?

Z(impedance)= R(resistance) + jX(reactance)

Y(admittance)=G(conductance)+jB (susceptance)

I never measured admittance,conductance,susceptance
so i don't really know much about these

Does this stuff change with frequency?
Y(admittance)=G(conductance)+jB (susceptance) change with frequency?

You can express circuits in AC by Z or Y, it's depend on further calculations. But most of us familiar with Z.( like we familiar with R).

If you have a chance try to connect simple circuits like 1kΩ resistor series with 1mH inductor. connect to 1V DC voltage. Measure your current. You will see I=V/R. That mean inductor is short circuit in DC.

(for simple, I assume ideal inductor, no internal resistance. that's why your measured I will be a little smaller than calculation. But this is no problem in your case.)

Next try to connect simple circuits like 1kΩ resistor series with 1mH inductor. connect to 1Vrms 1kHz ac voltage. Measure your current. You will see I≠V/R.

Actual current will be I=V/Z or I=VY.

If you have a chance to use oscilloscope measure voltage across R and V supply with dual channel and you will see the effect of X or B.

Try to test this circuit and I hope this will answer all of your question.

If you still have questions we will discuss again.

MRFGUY for helping me out on this


Whats the difference between Admittance VS Impedance?
1.) A measure of the ability of a reactive circuit to permit current
2.) The reciprocal of impedance
3.) ( Y )


Whats the Difference between Conductance (G) VS Resistance?
1.) The ability of a circuit to allow current
2.) The reciprocal of resistance


Inductive Susceptance (B)(L)
1.) The Ability of a inductor to "PERMIT" current
2.) The reciprocal of inductive reactance


Capacitive Susceptance (B)(c)
1.) The Ability of a capacitor to "PERMIT" current
2.) The reciprocal of capacitive reactance


This is my main problem is this

:Conductance (G) is the reciprocal of resistance:

What does this mean the reciprocal of resistance
What is conductance?
is Conductance
a.) ohms?
b.) what is it really?
Does the reciprocal- mean its the opposite of resistance?

:Susceptance (B) is the reciprocal of reactance:

What does this mean the reciprocal of reactance
What is susceptance?
is susceptance
a.) ohms?
b.) reactance buts its not reactance its a different kind of
reactance but what kind i never measured this for a
circuit im new to this susceptance reactance?

: Admittance (Y) is the reciprocal of impedance :

What does this mean the reciprocal of impedance?
What is admittance
is admittance
a.) ohms?
b.) impedance but what kind is this "admittance impedance"?

convert susceptance to reactance

Thanks guys for help on this stuff

Can you please give me like a water analogy for these terms
admittance,conductance,susceptance?

This inverse is not making sense to me at all i need another way
to look at these terms because i can't picture these in my mind

This inverse is my main problem this inverse doesn't make sense
to me at all what really is a inverse because this is applied inverse
to a compondent or a circuit so its the inverse

I have some questions Please don't say its the inverse of resistance,
impedance, reactance this inverse doesn't explain to me why or
what Admittance , Conductance , Susceptance Does?

Compondent questions:

A resistor has 1.) Admittance? but what is it? what does it do?
2.) Conductance? but what is it? what does it do?
3.) susceptance? but what is it? what does it do?

a Capacitor has 1.) Admittance? but what is it? what does it do?
2.) Conductance? but what is it? what does it do?
3.) Susceptance? but what is it? what does it do?

a Inductor has 1.) Admittance? but what is it? what does it do?
2.) Conductance? but what is it? what does it do?
3.) Susceptance? but what is it? what does it do?

circuit questions:

Every circuit has 1.) Admittance? but what is it? what does it do?
2.) Conductance? but what is it ? what does it do?
3.) Susceptance? but what is it? what does it do?

calculate admittance

walters,

pls stop wondering about those things.

First, at least, try to connect the the simple circuits (or even you can use orcad to simulate) and check the results as i mention previously. You can change the frequency, value of C, L , R and you can easily notice the results. Base on your results, I think the discussion can be going on.

capacitor admittance

Yes i use electronic workbench but i can't measure these terms i have problems
understanding them

Can you please give me good meaning of these terms to me

combine susceptance

I've never been used E.Wbench. I normally used orcad. But any how I think you can easily measure voltage, current. But I think you can't measure Z,Y,X,B and directly from that simulator. (Those measurement can be done in HF software like ansoft designer,....)

Try to setup the circuit and measure V and I of all components. ( Calculate R, X ) and you can find Z (keep in your mind that Z is complex no.)

same as for Y.
