(V) is the electric potential difference (Delta varphi) between the conductors. It is known as the voltage of the capacitor. It is also known as the voltage across the capacitor. A two-conductor capacitor plays an important role as a component in electric circuits. The simplest kind of capacitor is the parallel-plate capacitor.

Capacitor-switching transients typically occur when a large capacitor on the high-voltage side of the power system (usually at the utility side) is ener- gized. This results in magnification of transients at low-voltage capacitors. The magnified transient at a low-voltage remote end can reach up to 400% of its rated values. Overvoltages.

Suppose that Voー495020° y (rms). A capacitor is placed in parallel with the 150 kVA load and is adjusted until the steady-state voltage at the sending end of the line has the same magnitude as the voltage at the load end, that is, 4950 V (rms).
Derivation for voltage across a charging and discharging capacitor
When the switch ''S'' is closed, the current flows through the capacitor and it charges towards the voltage V from value 0. As the capacitor charges, the voltage across the capacitor increases and the current through the circuit gradually decrease. For an uncharged capacitor, the current through the circuit will be maximum at the instant of ...
