alleryHeat produced in a resistor in time t (Joule's law) is:
AH = V t
BH = I R t
CH = I² R t
DH = I t² / R
Answer & Solution
Correct answer: C. H = I² R t
1. Joule heating: H = I² R t (energy dissipated as heat).
2. Equivalent forms: H = V² t / R = V I t.
3. Basis for heaters, irons, kettles, electric ovens.
