Question
A parallel-plate capacitor having plates 6.8cm apart is connected across the terminals of a 12V battery.
Part A
Being as quantitative as you can, describe the location of the equipotential surface that is at a potential of 6.4V relative to the potential of the negative plate. Avoid the edges of the plates.
Express your answer using two significant figures.
3.62
Part B
Do the same for the equipotential surface that is at 2.6V relative to the negative plate.
Express your answer using two significant figures.
1.47
Part C
What is the potential gradient between the plates?
Express your answer using two significant figures.
Part C only please
Explanation / Answer
partC
Potential gravdient = V/d = E
so PG = 12/0.068
PG = 176.4 V/m
