A capacitance of 100 fiF is connected in series with a resistance of 8000 £2. The time constant of the circuit is______________?

Correct answer: D. 0.8 s

  • A. 0.2 s
  • B. 0.4 s
  • C. 0.6 s
  • D. 0.8 s

Explanation

For an RC circuit, the time constant is τ = RC. With R = 8000 Ω and C = 100 μF, τ = 8000 × 100 × 10⁻⁶ = 0.8 s.
