Analysis & Explanation

The expression (i) $\mathrm{Q} = \mathrm{I}\times \mathrm{t}$ is derived from the definition of electric current, which is the rate of flow of electric charge. The expression (ii) $\mathrm{W} = \mathrm{V}\times \mathrm{Q}$ is derived from the definition of electric potential difference, which is the work done to move a unit charge from one point to the other.
