Hi, how to add other heterogeneous part for a part like relay in orcad cadence, if you want to add later. for example the DPDT relay has 3 parts namely coil, NONC1 and NONC2. i prefer to add coil part now in schematic and NONC1( L13A) and NONC2(L13B) part later. my question is how to invoke the...
hi, can any one clarify about the following things WRT to I/O pins on 89s52 micro controller. kindly refer attached image.
1, What is the meaning of IOL = 1.6mA, with respect to VOL(0.45 V max)? is it minimum sink current when no output is connected?
2, similarly for VOH, IOH = -60uA? how is...
Hello, with respect to the below image how much will be current flow through the switch and resistor R2 when it is pressed?
assuming that the capacitor is fully charged and resistance offered by the switch is zero.
will it be 5V/10 = 0.5A. if that is the case then maximum current carried by...
hi, which is the efficient way to measure voltage in a bidirectional source. for example H bridge output at OP1 and OP2. a voltage divider and follower at either end measured with ADC or through a bridge rectifier at OP1 and OP2 then voltage divider, follower and ADC (to save one set of voltage...
Re: capacitor selection for high current circuit?
how to determine ripple current and ripple frequency, is it dependent/independent of load current? 100A is max rush current, generally load current around 20A will flow.
the design has both DC and AC(SMPS). SMPS is for driver circuit...
hi, generally i choose 100 to 1000uF capacitor as filter for micro controller based circuit for lower amps.
on what basis the filter capacitance value should be chosen? how is it related with load current? presently designing a circuit for 100A. max operating voltage is 25.
note: for similar...
ok. lets assume V1 =10V, i am putting LM317 regulator instead of V2 (or U) designed for 5v and R =1.2Ω. with respect to the formula (V1 - V2)/R I will be around 4A.
is LM317 is capable of sinking this current? if yes then how can we know the current sinking capability of the regulator. if no...
my target is voltage. i just want to understand what will be the current flow path in the circuit.
how it will flow through V2, when it gives opposing voltage?
hope my question is clear.
thanks
hi, let me brief my question with updated picture.
U is a circuit made of "opamp/MOSFET" (not sure how the design will be) is operated by its own power supply Vsource. U is a variable voltage generator circuit , which is always less than E. the positive side of U faces E's positive so that the...
Are you sure you want 3 variable values:
V1: 11V ... 14.4V
R1: to set the desired current
V2: variable voltage
Now what value can you rely on?
No. that's why i gave voltage as 12 and resistance(fixed) value based on max current required. only V2 will be variable.
Linear: This means a lot of...
sorry, if my question was not clear.
* I don´t see the use of this circuit.
this circuit is used for a simulating application, where load current is determined by voltage(V2).
* Is V2 a linear circuit or a switching circuit?
linear circuit.
* 12V battery voltage source: What chemistry? If...
hi, what are the challenges/possibilities to design the below circuit.
V1 is a 12V battery source. r1 is power resistor with value less than 1 ohms(based on requirement). V2 is the electronic circuit (using FET or OPAMP etc) with its own operating supply. V2 is always less than V1 so current...
