An AC source is rated 220 V 50 Hz The average voltage is calculated in a time interval of 0 01 s It 1 must be zero 3 is never zero 10 The magnetic field energy in an inductor changes from maximum value to minimum value in 5 0 ms when connected to an AC source The frequency of the source 2 may be zero 4 is 200 2 v is 1 20 Hz 3 200 Hz An AC source producing emf cos 100 m t cos 500 t is connected in series with a capacitor and a resistor The steady state current in the circuit is found to be i i cos 100 m t i cos 500 m t Mizi 2 i i 2 50 Hz 4 500 Hz
