alleryHeating power in a conductor is proportional to which expression?
AI divided by R
BV divided by I
CI squared times R
DR divided by I
Answer & Solution
Correct answer: C. I squared times R
1. Joule's law gives power P proportional to I squared times R.
2. The other expressions do not follow that relation.
3. So I squared times R is correct.
