Capacitors
When a potential difference V exists between the two plates, one holds a charge of + Q and the other holds an equal and opposite charge of − Q.The total charge is zero, Q refers to the charge which has been moved from one plate to the other. The voltage between the plates and the charge held by the plates are related by a term known as the capacitance of the …
