Answer:
To calculate the energy consumption for each appliance, we will first convert the power ratings to kilowatts (kW) and then use the formula:
Energy (kWh) = Power (kW) x Time (hours)
1. Energy consumed by 5 x 60W light globes for 17 minutes each:
Total power = 5 x 60W = 300W = 0.3 kW
Time = 17 minutes = 17/60 hours = 0.2833 hours
Energy = 0.3 kW x 0.2833 hours = 0.085 kW-hours
2. Energy consumed by 1 x 120W television for 2.2 hours:
Power = 120W = 0.12 kW
Time = 2.2 hours
Energy = 0.12 kW x 2.2 hours = 0.264 kWh
Therefore, the total energy consumed by using 5 x 60W light globes for 17 minutes each and 1 x 120W television for 2.2 hours would be:
0.085 kWh + 0.264 kWh = 0.349 kWh
So, the customer would have consumed 0.349 kWh of energy.
