|
Answer» Answer: Given parametersPower rating of the device (P) = 500 W = 0.50 kWTime for which the device RUNS (T) = 10 hENERGY CONSUMED by an electric device can be OBTAINED with the HELP of the expression for power,P = W/TWork done = Energy consumed by the device∴ Energy consumed = Power × TimeEnergy consumed = 0.50 × 10Energy consumed = 5 kWhHence, the energy consumed by four equal rating devices in 10 h will be⇒ 4 × 5 kWh= 20 kWhExplanation: hope it is helpful to you.. ☺☺✌✌ |
