C)the time required to charge to 63% or discharge to 37%.
D)all of these.

Question

Quizplus · Accepted Answer

The time constant of a capacitor, denoted by τ (tau), is given by τ = RC, where R is the resistance and C is the capacitance. It represents the time required for the voltage across the capacitor to charge to approximately 63% of its final value or discharge to about 37% of its initial value. Thus, all statements are correct.
