Impedance of a series LR circuit is `25 Omega`. If the resistance is `20 Omega`. Find the reactance.

The current through an AC circuit depends on the magnitude of the applied voltage and impedance of the circuit:-A sinusoidal voltage of peak value 283 V and frequency 50 Hz is applied to a series LCR circuit in which R = 3Omega , L =25.48 mH, and C = 796 muF . Find the impedance of the circuit

Calculate the impedance of a coil of resistance 3 Omega and reactance 4 Omega

When two resistors are connected In series, the effective resistance is 5 Omega . When they are connected In parallel, resistance is 6//5 Omega . Find the Individual resistances.
