Consider a region in space where a uniform electric field E

Consider a region in space where a uniform electric field E = 6410 N/C points in the negative x direction. What is the distance between the +12.7 V and the +13.7 V equipotentials?

Solution

delta V = E * d

delta V = change in potential, E = electric field , d = distance

d = delta V / E

= (13.7 - 12.7) / 6410

= 0.000156 = 0.15 mm
