1.	The potential difference across a conductor is doubled, the rate of generation of heat will:A. become one-fourthB. be halvedC. be doubledD. becomes four times
Answer» Heat generated is given by, H = \(\frac{V^2}{R}\,t\) H ∝ V² Hence, with doubling of the potential difference, the heat produced will be four times.

Answer»

Heat generated is given by,

H = \(\frac{V^2}{R}\,t\)

H ∝ V²

Hence, with doubling of the potential difference, the heat produced will be four times.
