Assignment

1. A circuit has an inductance of 1/π Henry and resistance 2,100 Ω. A supply of 50 cycles AC is applied to it. Calculate the reactance and impedance offered by the circuit.
2. Construct an electric circuit with inductance of 5 Henry and parallel combination of resistance of 10 Ω and 25 Ω as shown in the figure below. If V_RMS is 100 Volt, find out the frequency at which the total current through the circuit is 318.2 mA.

3. Calculate the voltage drop across the resistance R1.

4. What is the power of a 25 V_AC series RL circuit when R = 50 Ω and X_L = 1000 Ω?
5. What will happen if the inductor shorts out in the given circuit?
