Explanation:

CalculatorsElectrical, RF and Electronics Calculators

Example: Calculating the time constant of the RC circuit with 3.3microfarad capacitor and 3.3ohm resistor

Scheme

This RC circuit calculator will calculate the maximum current Imax at the beginning of the capacitor charging, the maximum energy Emax and maximum charge Qmax in the capacitor when it is fully charged, for the given voltage across it as well as the time constant τ in the RC circuit.

Example: Calculate the time constant, max. energy, max. current and max. charge for an RC circuit consisting of a 2 kΩ resistor and 5 μF capacitor connected in series. The circuit is connected to a 10 V DC power supply. Note that the voltage is not necessary for the RC circuit time constant calculation.

The time constant is determined as

Formula

where τ is the time constant in seconds, R is the resistance in ohms and C is the capacitance in farads. The time constant of an RC circuit is defined as the time it takes for the capacitor to reach 63.2% of its maximum charge capacity provided that it has no initial charge. Note that the capacitor will be 63.2% charged after τ and almost fully charged (99.3%) after approximately 5τ.
