Question
If the price of 1 unit of electricity is Rs 10 then
calculate the cost of running a tractor of 20 HP having electric motor having 100% efficiency in 100 working hoursSolution
Horsepower (HP) to Kilowatts (kW): 1 HP = 0.746 kW Therefore, 20 HP = 20 × 0.746 = 14.92 kW Power Consumption for 100 Hours: Power consumed = Power (in kW) × Time (in hours) = 14.92 kW × 100 hours = 1,492 kWh Cost Calculation: Cost = Power consumed (in kWh) × Price per unit = 1,492 kWh × ₹10 = ₹14,920
