Question

Answer my question , First answer will be marked as brainliest--------​

Answer 1

Given,

Resistance, R = 8Ω

Current, I = 15 A

Time,T=2h =2×60×60 = 7200sec

Heat developed ,H = I² × R × T

= (15)² × 8 × 7200

= 225 × 8 × 7200

= 12960000 J

= 12960 kJ

Thus, the heat developed is 12960 kJ (kilojoule).
