Capacitor banks in power system (part 1)
If V = 1 Volt than C = Q, thus capacitance is defined as the amount of electric charge in coulomb required to raise its potential by one volt.. If V = 1 Volt than C = Q, and Q = 1 Coulomb than C = 1 Farad thus one Farad is capacitance of a capacitor which stores a charge of one coulomb when a voltage of one volt is applied across its terminal.
