The current produced is defined as the ratio between the charge flowing in a certain part of the circuit divided by the time interval considered: [tex]I= \frac{Q}{\Delta t} [/tex] where I is the current Q is the charge [tex]\Delta t[/tex] is the time interval
The cell in our problem produces a current of I=125 A and the charge is [tex]Q=8.26 \cdot 10^6 C[/tex], so to calculate the corresponding time we can re-arrange the previous equation, and we find [tex]\Delta t= \frac{Q}{I}= \frac{8.26 \cdot 10^6 C}{125 A} =6.61 \cdot 10^4 s [/tex]
