Resonant Voltage Rise Calculator

Calculate resonant voltage rise with the Resonant Voltage Rise Calculator, and learn how with the integrated live example

The formula to calculate resonant voltage rise is:


Q = Q Factor
E = Applied voltage

Example: Calculate the resonant voltage rise of a coil that has a Q factor of 580 and the applied voltage is 30 volts

V_{r} =30\times 580=17,400\; volts

Enter the Applied Voltage and Q Factor
