A)the time required to charge to 63% or discharge to 37%.
B)directly proportional to the resistance in the circuit.
C)directly proportional to the capacitance in the circuit.
D)all of these.

Quizplus · Accepted Answer

The time constant of a capacitor is defined as the time it takes for the voltage across the capacitor to reach 63% of its maximum value during charging or to decrease to 37% of its maximum value during discharging. This time constant is directly proportional to both the resistance and the capacitance in the circuit, as described by the formula τ = RC, where τ is the time constant, R is the resistance, and C is the capacitance. Therefore, all the statements A, B, and C are correct, making D the correct choice.
