(C) The terminal voltage $V$ of a battery is given by the formula $V = E - Ir$, where $E$ is the $e.m.f.$, $I$ is the current, and $r$ is the internal resistance.Given:$E = 15\, V$$I = 10\, A$$r = 0.05\, \Omega$Substituting these values into the formula:$V = 15 - (10 \times 0.05)$$V = 15 - 0.5$$V = 14.5\, V$Therefore, the terminal voltage is $14.5\, V$.
