How does the time constant of a capacitive circuit change with variations in capacitance and resistance?

Show Answers

It grows when both capacitance and resistance decreaseIt becomes larger as capacitance decreases and resistance increasesIt rises when capacitance increases but resistance decreasesIt increases when both capacitance and resistance increaseIt remains zero regardless of changes

Explanation

The time constant (τ) of a capacitive circuit is given by the product of resistance (R) and capacitance (C), τ = R × C. Therefore, the time constant increases when both resistance and capacitance increase.
