Question

a battery can supply a charge of 2.5*10^3 C .if the current is drawn from the battery at a rate of 12.5 A ,calculate the time in which battery will get discharged.

Answer 1

Charge(q) =
$$\begin{gathered} 2.5\times {10}^{3}C,current\left(I\right)=12.5A \\ I=\frac{charge\left(q\right)}{timetaken} \\ t=\frac{q}{I}=\frac{2.5\times {10}^3}{12.5}=0.2\times {10}^{3}s=200s \end{gathered}$$
