Question

The capacitive time constant of the RC circuit shown in the figure is:

• A. zero
• B. Infinity
• C. 2s
• D. 2$\mu$s

Answer 1

Answer: (B)

Infinity

Since both the terminals of the capacitor are shorted, the effective capacitance of the capacitor becomes infinity.

Hence, the time constant becomes $RC=1\Omega \times \infty$ $=\infty$
