Question

The potential difference across a conductor is
doubled. The amount of heat generated per
second will be :​

Answer 1

Answer:

Heat generated is given by, Hence, with doubling of the potential difference, the heat produced will be four times.

Explanation:

MARK BRAINLIEST PLEASE

Answer 2

Answer:

the heat will also be doubled

Explanation:

the heat generated in conductor is directly proportional to the current flowing through it  

IE ,  H is proportional to I

but from ohms law we know that

  V is directly  proportional to I

since  H is directly  proportional to I  and V is  directly proportional to I .

heat is  directly proportional to the potential difference

therefore potential difference is doubled . heat will also be doubled
