Problem

A dry cell in a torch delivers

180\,\text{J}

of electrical energy while sending

450\,\text{C}

of charge around the circuit. a. (i) Calculate the potential difference provided by the cell in volts. b. (ii) Write the value obtained in part (i) in base SI units. c. (iii) If the same cell drives a current of

0.25\,\text{A}

for

2\,\text{min}

, determine the additional work done in that time. Show all unit conversions clearly.
