"A 12 HP motor has to be operated 8 hours/day. How much will it cost at the rate of 50 paisa/kWh in 10 days"
Added by Ashu G.
Step 1
Given: Power of motor = 12 HP = 12 * 746 watts Time motor is operated per day = 8 hours = 8 * 3600 seconds Total days motor is operated = 10 days Energy used = Power * Time Energy used in 1 day = 12 * 746 * 8 * 3600 Energy used in 10 days = 12 * 746 * 8 * 3600 * Show more…
