The capacitive time constant of the RC circuit shown in the figure.

A

zero

B

infinity

C

2 s

D

`2 mu s`

Text Solution

Verified by Experts

The correct Answer is:
B
Since capacitor is shunted by a wire, its capacity becomes infinity. This , `C = oo`
Time cosntant = RC = `1 xx oo = oo` = infinity.
