JEE Previous Year Question
A uniform heating wire of resistance is connected across a potential difference of 240V. The wire is then cut into half and potential difference of 240V is applied across each half separately. The ratio of power dissipation in first case to the total power dissipation in the second case would be 1:x, where x is...........
