Time constant of a capacitive circuit__________?
Correct answer: D. increase with increase of capacitance and increase of resistance
- A. increases with the decrease of capacitance and decrease of resistance
- B. increases with the decrease of capacitance and increase of resistance
- C. increases with the increase of capacitance and decrease of resistance
- D. increase with increase of capacitance and increase of resistance
Explanation
For a capacitive circuit, the time constant is τ = RC. It increases when both resistance and capacitance increase, so option d fits.
