Time Response of Reactive Circuits - Engineering

Q1:

When a 24 V input pulse with a width equal to five time constants is applied to an RC integrator, the capacitor charges to

A 24 V

B 15.12 V

C 20.64 V

D 12 V

ANS:A - 24 V

We know that,

v = v(total)*(1-exp^-t/RC).

= 24*(1-exp^-5) (i,e T=5RC) .

= 24 V.
