If the rms current ina 50 Hz a.c. circuit is 5 A, the value of the current 1/300 seconds after its value becomes zero is:

The equation of alternating current for a circuit is given by I = 50 cos 100 pit find the value of current 1/300 second after it was zero.

In an a.c. circuit, the current

In an LCR-series a.c. circuit, the current

In an a.c. circuit, with phase voltage V and current I, the power dissipated is

A 2 mu F capacitor 100 ohm resistor and 8 H inductor are connected in series with an a.c. source. What should be the frequency of soure for which the current drawn in the circuit is maximum? If peak value of emf of the source is 200 V, peak value of current in the circuit.
