Time Response of Reactive Circuits - Engineering

Q1:

If a periodic pulse waveform has a pulse width and the time between pulses each equal to or greater than five time constants, the capacitor will

A partially charge and fully discharge during each period of the input waveform

B fully charge and partially discharge during each period of the input waveform

C fully charge and fully discharge during each period of the input waveform

D partially charge and partially discharge during each period of the input waveform

ANS:C - fully charge and fully discharge during each period of the input waveform

Capacitor fully charge and discharge in 5-time constants. Here pulse is ON for 5-time constants and gap between the pulses is also 5-time constant.

Hence capacitor is fully charged and fully discharged.
