My question is related to system Protection and it is:
"Generator impedance doe snot affect the fault current to a great extent in low-voltage distribution system. Explain?
I need the answer of this question. kindly help
I would like to perform and experiment in which i want to measure internal source resistance of function generator (as you can say to verify the internal source resistance of function generator is 50 ohm) so i can perform it on bread board.
I would like to give a question regarding to barrel 16 shifter in paper its code should be in VHDL. kindly anyone help me to provide me a question and its solution.. I'm new in VHDL language.
in my assignment it a condition to use 24vdc and variable resistor.
so in your diagram 10vdc is supply is it possible with 24vdc.??
and I measure the current levels like 4-8-12-16-20mA from emitter to ground ?? Am i right ??
I have a picture capture from internet regarding to 4-20mA current circuit..
kindly open this close picture.. and guide me ...

the problem is that when I apply this circuit then not get a linear relation e.g at Minimum value of resistance 20mA and at high value its 4mA but...
I would like to design a circuit of 4-20mA( which is most common circuit in industry application) with variable resistance...
selection of variable resistance is like that at Max resistance the current should be 4mA and when Mini resistance then the current should be 20mA.
How I design this...
means at minimun value of resistance its 20mA and then gradually with 25% of that selected resistance the current should be 16mA and so on. the supply voltage should be 24 volts..
kindly help it .. schematic diagram or that circuit
Hi,
I would like to design a circuit that give me 4-20mA current using variable resistance.
There are following requirments:
0% resistance 20mA
25% resistance 16mA
50% resistance 12mA
75% resistance 8mA
100% resistance 4mA
kindly help me out to design this circuit
Thankyou
What is inductor basically means if we untwist that coil and make it straight wire still it will be called inductor.. ??
kindly response me ...
Thankyou
