3.If P is the rate at which the battery delivers energy and ∆ t is the time, then ∆ E = P ∆ t is the energy
delivered in time ∆ t .If q is the charge that passes through the battery in time ∆ t and
E
is the emf of
the battery, then ∆ E = q
E
. Equating the two expressions for ∆ E and solving for ∆ t ,weobtain
∆ t = q
