Question

]
A parallel plate capacitor is charged by connecting it to a battery. The battery is
then disconnected and the distance between the plates is doubled. This doubles.
a] The electric field at each plate
by The potential difference between the conductors
c] The charge density on each conductor
d] The stored energy
P​

Answer 1

Answer:

c

Explanation:

because it will double

Answer 2

Answer:

The potential difference between the conductors will increase by two times

Explanation:

• A capacitor stores electric energy in an electric field
• Capacitors are found in fans, refrigerators, computers etc
• Capacitors have two terminals, one positive and negative
• Parallel plate capacitors consist of two parallel conducting plates which are connected across a cell
• The plates become charged and there is a formation of an electric field
• Capacitance is the ratio of stored charge to the potential difference between the two terminals
• When the distance between the plates is doubled, the value of the charge does not change, only the capacitance will decrease
• Capacitance is inversely proportional to potential difference
• Potential difference will double
