The capacitance C is charged through a resistance R. The time constant of the charging circuit is given by__________?
Correct answer: C. RC
- A. CIR
- B. 1/RC
- C. RC
- D. RIC
Explanation
For a first-order RC charging circuit, the time constant is the product of resistance and capacitance, τ = RC. It represents the time to reach about 63.2% of the final capacitor voltage.
