Taken into account the above equation for capacitor discharge and its accompanying circuit, the variables which make up the equation are explained below: VC- VCis the voltage that is across the capacitor after a certain time period has elapsed. V0- V0is the initial voltage across the capacitor...
Therefore, it takes a shorter time to discharge that charge. Therefore, the higher the capacitance value, the greater VC will be. The smaller the capacitance, the smaller VC will be. The value of the equation result gives VC, which is the voltage that is across the capacitor. The ...
The rate of stored energy discharge in capacitors is quiet high but with low storage capacity. Quantity of stored energy is usually defined in terms of voltage over the capacitor. The following equation further describes the correlation: (9.9)W=12Q2V=12C·V2 where W is the stored energy on ...
As you turn on the power supply, the current begins to flow through the capacitor inducing the positive and negative potentials across its plates. The capacitor continues to charge until the capacitor voltage equalizes up to the supply voltage which is called as the charging phase of the capacit...
An overvoltage preventing circuit 20 cuts off the primary current of a transformer 2 until the voltage of the main discharge capacitor 12 becomes smaller than the predetermined voltage. The following equation is satisfied: VA<2VD<2>-VC<2>, where VD is the rated voltage of the main discharge...
