RC time constant calculator
Calculates the time constant of a resistor-capacitor circuit. Time constant is the time required to charge or discharge the capacitor by ~63.2% of the difference between the initial and final value.
|Example 1: Must calculate the time constant of a 47uF capacitor and 22 ohm resistor||View example|
You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga
|Time constant||1.034 milliseconds|
|Rise time from 20% to 80%||1.4476 milliseconds|
|Rise time from 10% to 90%||2.2748 milliseconds|
|3dB cutoff frequency||~153.921608 hertz|
