C) CR time variable
D) RC time variable

Question

Quizplus · Accepted Answer

The time needed to charge a capacitor in a circuit with a resistor is called the RC time constant. It is a measure of the time it takes for the voltage across the capacitor to reach approximately 63.2% of its maximum value after a sudden change in voltage. This time constant is calculated as the product of the resistance (R) and the capacitance (C) in the circuit.
