Capacitor Discharge
When do capacitors discharge? Capacitors discharge when another path in the circuit that allows the charges to flow to each other is created. This causes the charges to flow out of the capacitor, and the capacitor becomes discharged
Air-Core Reactors Dry Type
Harmonic filter reactors, in association with capacitor units and occasionally resistors, create a filter circuit tuned to a certain frequency (resonance frequency) so as to reduce, block or provide a low impedance path for the harmonic currents in the audio frequency range. They are connected either in a parallel or in a series configuration.

RC Discharging Circuit Tutorial & RC Time Constant
As we saw in the previous tutorial, in a RC Discharging Circuit the time constant ( τ ) is still equal to the value of 63%.Then for a RC discharging circuit that is initially fully charged, the voltage across the capacitor after one time constant, 1T, has dropped by 63% of its initial value which is 1 – 0.63 = 0.37 or 37% of its final value. Thus the time constant of the circuit is given as
