Time Response of Reactive Circuits - Technical MCQs

Q1:

After the rising edge of the input pulse occurs, it takes ______ for the voltage across the resistor to decrease to zero in the given circuit.

A 0 s

B 68 mu.gifs

C 340 mu.gifs

D 500 mu.gifs

ANS:C - 340 mu.gifs

T =RC,
T = 680 * 0.1 * 10^-6,
T = 68 u sec.

The voltage across the resistor to decrease to zero in the given circuit, it needs 5 Time.

Constants.
5T = 5 RC = 5 * 68 * 10^-6,
5T = 340 u sec.
