How much energy is consumed when a current of J amperes flows through the filament (or element) of a heater having a resistance of 100 ohms for two hours ? Express It in joules.

Answer»

Energy(E) = VOLTAGE (V) × Current (I) × Time (t)and V = I×R (Resistance)So we get that E = I^2 × R × tPutting values of I, R and t we get =>E = 5^2 × 100 × 2E = 25 × 100 × (2×60×60)So the ans. is 18000000 joules = 18 mega jouleplease mark as BRAINLEST answer
