RC time constant calculator

This calculator will help you to calculate the time constant when using a Resistor and Capacitor in series. This can be used to calculate Resistor or Capacitor for a given time in seconds. You need at least two inputs in this calculator.

  • Resistor, Capacitor, Time – Input / Output

FORMULAS:

To determine Time in seconds T = RC  To determine R R = T / C To determine C C = T / R
