Capacitor
A parallel plate capacitor is constructed with circular plates of radius 0.750 cm and plate separation 0.0500 mm. If the capacitor is connected across a 37.2V source find.
(a) The capacitance.
(b) The surface charge in each plate.
(c) The energy stored in the capacitor.
(d) The electric field between plates.
(e) If a slab of plastic with dielectric constant K = 3.6 is inserted between the plates of the capacitor What will the capacitance be?
