RL Time Constant Calculator

The Time Constant Calculator calculates the time constant for either an RC (resistor-capacitor) circuit or an RL (resistor-inductor) circuit.
The time constant represents the amount of time it takes for a capacitor (for RC circuits) or an inductor (for RL circuits) to charge or discharge 63%.
A user enters in the resistance and either the capacitance or inductance and the time constant value is automatically computed. The resultant value is given above in unit seconds (s).
