Question
A battery can supply a charge of 25 × 104 C. If the current is drawn from battery at the rate of 2.5 A, calculate the time in which battery will discharge completely.
Solution
Charge = Q = 25 × 104 C
Electric current = I = 2.5A
Time = t = ?
I = `"Q"/"t"`
t = `"Q"/"I"`
t = `(25 xx 10^4)/2.5 = 10^5`s
t = 100000 s
