Answer:
Explanation:
(i). If three cells of 2 volt each are connected in series to make a battery, then the total potential difference between terminals of the battery will be 6V.
(ii).
a). Given: p.d. = 2V, Charge moved = 1C
We know that, p.d. = work done / charge moved
Work done = p.d. x charge moved = 2x1
Work done = 2 joules
b.) Given: p.d. = 6V, Charge moved =1C
Work done = p.d. x charge moved
= 6 x 1
Work done = 6 joule
