Question:medium

An electric coil is rated $400\text{ W}$, $200\text{ V}$. It is cut into two equal parts and connected in parallel to the same source of $200\text{ V}$. Calculate the percentage increase in energy produced per second.

Show Hint

When a wire is cut into $n$ equal segments and rearranged in parallel, the total power output increases by a factor of $n^2$. Here, $n=2$, so power becomes $2^2 = 4$ times the original. A $4$-times increase means a value becomes $400\%$, which stands for a $300\%$ net increase!
