An empty parallel plate capacitor is connected between the terminals of a 18.8-V battery and charges up. The capacitor is then disconnected from the battery, and the spacing between the capacitor plates is doubled. As a result of this change, what is the new voltage between the plates of the capacitor

Answer:


p.d' = 37.6 V

Step-by-step explanation:

From the question we are told that:

Potential difference
p.d=18.8V

New Capacitor
C_1=C_2/2

Generally the equation for Capacitor capacitance is mathematically given by


C=(eA)/(d)

Generally the equation for New p.d' is mathematically given by


C_2V=C_1*p.d'


p.d' = 2V


p.d'= 2 * 18.8


p.d' = 37.6 V
