Problem

A storage battery provides a steady current of

2.5\,\text{A}

to an external circuit for

8\,\text{h}

before it is fully discharged. (i) Calculate the total charge delivered by the battery during the discharge. (ii) The battery is rated at

40\,\text{Ah}

. Show whether this rating is consistent with your result in part (i). (iii) During recharging the average current is kept at

5\,\text{A}

. Estimate the time required to restore the battery to full charge, assuming

100\%

efficiency.
