Question

What is the time constant τ of an RC circuit?
Options
A τ = R/C
B τ = RC
Correct Answer
C τ = C/R
D τ = 1/(RC)
Correct Answer

Option B is the correct answer.

Detailed Explanation

The time constant τ of an RC circuit is the product of resistance R and capacitance C: τ = RC. Its unit is seconds.

Hint

Resistance × Capacitance.
