The capacitance of a parallel plate capacitor when the plates are separated by air or free space. A parallel plate capacitor with a dielectric between its plates has a capacitance that is sensitive to the dielectric constant of the material. The maximum electric field strength when an insulating material break down is called dielectric strength.

(Review Figure \(\PageIndex{1}\).) Often realistic in detail, the person applying the shock directs another person to “make it 400 joules this time.” The energy delivered by the defibrillator is stored in a capacitor and can be adjusted to fit the situation.

Without dielectric, the charge on the plates is \[Q_0 = C_0V_0 = (20.0 \, pF)(40.0 \, V) = 0.8 \, nC. \nonumber\] Since the battery is disconnected before the dielectric is inserted, the plate charge is unaffected by the dielectric and remains at 0.8 nC.
