The time it takes 62.

To solve for the RC time constant of any RC circuit is relatively simple, since it is

a capacitor to

merely a matter of multiplying the value of the resistance times the value of the

change its charge

by 63%.

Written as a formula: t = R x C

Resistance in ohms multiplied by capacitance in farads equals time in seconds.

This is the time it takes the capacitor to change its charge by 63%, and is the RC time

constant of the circuit.

The RC time constant of an RC circuit is found by the formula:

t=

x

.

This is the time it takes the capacitor to change its charge by

%.

t=RxC

Explain what is meant by the RC time constant of an RC circuit.

The time it takes 65.

An RC circuit with R of 10 ohms and C of 1 farad has an RC time constant

a capacitor to

change its charge

by 63%.

In this circuit, C will change its charge by 63% in

.
