A) 50%
B) 37%
C) 100%
D) 63%
E) 90%

Quizplus · Accepted Answer

The time constant (symbolized by τ) is equal to the product of the resistance (R) and the capacitance (C) in the circuit. It represents the time for the charge on the capacitor to reach 63.2% of its final value. Therefore, the answer is D, 63%.
