Question

Q.1 In a particular RL series circuit a voltage of 10 V at 25 c/s produces 100 mA, while the same voltage at 75 c/s produces 60 mA. Draw the circuit diagram and insert the values of the constants. At what frequency will the value of the impedance be twice that at 50 c/s.

Answer 1

Answer:

In the circuits Inductive Reactance X2 = 2π vL = 2π(50) × (0.5) = 50πΩ Let capacitance be C so, xc = 12πv c = 1100πc an current leads voltage (circuit ... More
