Question

Two 13.0-cm-diameter electrodes 0.59cm apart form a parallel-plate capacitor. The electrodes are attached by metal wires to the terminals of a 13Vbattery.

What is the charge on each electrode while the capacitor is attached to the battery?

What is the electric field strength inside the capacitor while the capacitor is attached to the battery?

What is the potential difference between the electrodes while the capacitor is attached to the battery?

What is the charge on each electrode after insulating handles are used to pull the electrodes away from each other until they are 1.0cm apart? The electrodes remain connected to the battery during this process.

What is the electric field strength inside the capacitor after insulating handles are used to pull the electrodes away from each other until they are 1.0cm apart? The electrodes remain connected to the battery during this process.

What is the potential difference between the electrodes after insulating handles are used to pull the electrodes away from each other until they are 1.0cm apart? The electrodes remain connected to the battery during this process.

Explanation / Answer

part a)

s=0.0059 m

A=pi(0.13/2)2

Q=CV

C=e0A/s

A=pi(d/2)2

part b)

electric field=Q/Ae0

part c)

potential=V=13 V

part d)

let s1=0.01 m

C1=e0A/s1

Q1=C1V

part e)

E1=Q1/Ae0

part f)

V=13 V
