If a 12-V battery delivers 100 J in 5 s, find (a) the amount
of charge delivered and (b) the current produced.
Given that voltage v= 12v.
Energy in joules W= 100J
Time t=5sec
(a)The amount of charge delivered is w = v*Q
Q = w/v
= 100/12
= 8.33C.
(b) The amount of current produced is I = Q/t
= 8.33/5
= 1.67A.
