An empty capacitor is capable of storing 1.0 × 10-4 J of energy when connected to a certain battery. If the distance between the
plates is halved and then filled with a dielectric (κ = 2.8), how much energy could this modified capacitor store when connected to the same battery?
1 answer:
Answer:
Explanation:
d = Distance between capacitors
V = Voltage
k = Dielectric
A = Area
= Permittivity of free space
Energy the capacitor stores
Capacitance is given by
The new capacitance will be
New energy will be
The energy the modified capacitor store when connected to the same battery is
