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.
