RC Time Constant Formula
The following formula is used to calculate the RC time constant of an RC circuit.
t = R * C
- Where t is the time constant (s)
- R is the total resistance
- C is the total capacitance
To calculate the RC time constant, multiply the total resistance by the total capacitance.
RC Time Constant Definition
An RC Time constant is defined as the product of the resistance and capacitance within a circuit and is a measure of the voltage loss with respect to time.

FAQ
A time constant is a measure of the voltage loss across an RC circuit with respect to time. It’s completely dependent on the capacitance and the resistance of the circuit.
Resistance is a force acting against the flow of electricity or electrons.
