noun. the capacitance of a capacitor that has an equal and opposite charge of 1 coulomb on each plate and a voltage difference of 1 volt between the plates.
1. Noun, singular or mass A capacitor the size of one farad is quite large as it can store lots of charge. 2. Adjective If you multiply the ohm value of a resistor by the farad value of a capacitor, you get a time value measured in seconds; as resistance increases, the circuit’s time period also increases.
