Time Response of Reactive Circuits

Q1:

When a 12 V input pulse with a width equal to one time constant is applied to an RC integrator, the capacitor charges to

A 0 V

B 12 V

C 6.3 V

D 7.56 V

ANS:D - 7.56 V

As we are giving 12V supply,and our integrator is having a time constant of RC. thus, the capacitor will be charged to 63.8% of the applied supply voltage. hence its value will be equal to 12*63.8%=7.56V.

Hope my analysis is right.
