Concept simulation 20.4 provides background for this problem and gives you the opportunity to verify your answer graphically. how many time constants (a decimal number) must elapse before a capacitor in a series rc circuit is charged to 65.0% of its equilibrium charge?

The time constant is 1.049.

Explanation:

Given that,

Charge

We need to calculate the time constant

Using expression for charging in a RC circuit

Where, = time constant

Put the value into the formula

Hence, The time constant is 1.049.

the answer is d
