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.
