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
.
