    Dear all,

    I was asked to use Pspice to simulate the circuit below. Please help me to construct the circuit diagram with Pspice , thank you very much!![​IMG]

    actually, i have done it but i cannot simulate it, it keep telling me that "ERROR -- Voltage source and/or inductor loop involving V
    You may break the loop by adding a series resistance "

    Do exactly as the program suggests. Add a very small shunt resistance (1 ohm or less) between the two inductors.

    PSpice doesn't accept a loop that contains only a source and a coil.

    Thanks for helping!
    But the problem is will the circuit voltage and current change after the addition of the resistor?

    If the resistance is very small the outcome will vary by very little. The "qualitative" properties of the result won't change.
