Q#1 Transient Analysis GATE EE 1999 MCQ +2 marks -0.66 marks

A rectangular voltage pulse of magnitude V and duration T is applied to a series combination of resistance R and capacitance C. The maximum voltage developed across the capacitor is:

v

Explanation:

The rectangular pulse would be applied to series RC circuit as shown below,

C:\Users\Ankit\Dropbox\GATE papers\EE papers\Solutions\network\Network 91-01\Network Images\58.jpg

During the interval 0 < t < T

Supply Voltage v(t) = V

The equation of capacitor voltage can be determined on the basis of standard charging RC circuit.

At t = T,

For the interval t > T, v(t) = 0

So, the circuit behaves as discharging RC Circuit.

Thus, the voltage exponentially decays after t=T and hence maximum voltage occurs at t = T.
