Question

In an ac circuit an alternating voltage e =200√2 sin 100 t V is connected to a capacitor of capacity 1μF.

Answer 1

Answer:

The rms value of the current in the circuit is 20 milliAmperes. This is because we know that Vrms = alternating voltage / root under 2. We also know that Irms = Vrms / Xc = 200 / 1 / 100 X 10 to the power -6 = 2 X 10 to the power -2 = 20 milli Amperes. The root mean square value of any entity is the square root of the mean value of the squared values of the entity that is determined over an interval.
