RC Time Constant Calculator

Last Updated on January 28, 2021 by Krunal Shah

This calculator helps you to calculate time constant of RC circuit. The product of resistance and capacitance values is known as RC Time Constant.

How to use the calculator?

  • For this calculator, enter the voltage value.
  • Enter the capacitance value in micro-farads.
  • Enter the load resistance in ohms.
  • The calculator would show automatically the calculated value.

How to calculate RC Time Constant?

You can calculate the RC Time Constant with the help following formula:

τ = C X R

Example: Let us say you have 12 V supply voltage. The load is of 100 ohms. The time constant would be 0.000350 seconds.
