E and RC Calculator – calculating energy and time constant

Capacitor energy is energy stored elect statically all capacitors have two electrical conductors separated by insulator.
RC time constant is the time used to charge or discharge the capacitor and this charging or discharging is done through resistor.
This online calculator has been devised to determine load resistance and capacitance values.

E and RC

To calculate capacitor energy and time constant:

  • Voltage across capacitor (V)


  • Capacitance (C)


  • Load Resistance (R)



  • T (RC)


  • E
