CONCEPT:
The heat dissipated is given by:
Heat (H) = I2 R t
Work done (W) = Heat (H) = Energy consumed (E) = Power (P) × Time taken (t)
Where I = the current flowing in the circuit, R = the resistance of the circuit, and t = the time taken
CALCULATION:
Given,
Power = 100 W, Time = 8 hours per day
We know that,
Power (P) = Energy (E)/Time (t)
Power = 100 W = 0.1 KW
0.1 = E/8
Energy (E) = 0.8 KWh = 0.8 Unit in one day
Additional Information
1 Unit of electricity = 1 KWh = 1000 Watt-hour = 3.6 × 106 J
1 Kilo-watt = 1000 Watt
1 Hp = 1 horsepower = 746 Watt (W)
