Question
In the circuit shown in the figure, the value of (in Volts) for is _____
Correct answer
31.24 to 31.26
Solution
As the 10 A source is DC and the inductor is a short circuit.Let be the voltage of the top node (bottom node = reference). Two branches hang between the top node and ground:
1.Right branch: inductor (short) in series with the 5 resistor, carrying :
2.Middle branch: the dependent voltage source (+ at the top) in series with 5 . Its current downward is
KCL at the top node:Hence V.Answer: 31.25Continue learning with Success Tracker
