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
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.
