I A parallel-plate capacitor having plates 6.0 cm apart is connected 12 V battery. (a) Being as quantitative as ribe the location and shape of the equipotential sur- face that is at a potential of +6.0 V relative to the potential of the negative plate. Avoid the edges of the plates. (b) Do the same for the equipotential surface that is at +2.0 V relative to the negative plate. across the terminals of a ou can, desc (c) What is the potential gradient between the plates?

Explanation / Answer

23.

a)

Since electric field is given by

E=V/d

Electric field at negative plate due to positive plate

E=12/0.06 =200 V/m

Now

d=6/200=0.03 m =3 cm

b)

For V=2 V

d=2/200 =0.01 m =1 cm

c)

E=12/0.06 =200 V/m
