Time Response of Reactive Circuits - Technical MCQs

Q1:

The _____ is the time it takes for a capacitor to fully charge or discharge.

A transient time

B pulse response

C time constant

D steady state

ANS:A - transient time

The charge on the plates of the capacitor is given as Q = CV.

This charging (storage) and discharging (release) of a capacitor's energy is never instant but takes a certain amount of time to occur with the time taken for the capacitor to charge or discharge to within a certain percentage of its maximum supply value being known as its Time Constant ( τ ).
