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.
