Question

State whether given statement is True or False
Five time constants are required for a capacitor to charge fully or discharge fully.

• A. True
• B. False

Answer 1

The correct option is A True

When a resistor is connected in series with the capacitor forming an RC circuit, the capacitor will charge up gradually through the resistor until the voltage across the capacitor reaches that of the supply voltage. The time also called the transient response, required for the capacitor to fully charge is equivalent to about 5 time constant.

Hence the given statement is true.
