Answer:
Cost of energy = N230.4
Explanation:
Given the following data;
Time = 8 hours
Power = 1200 W
Voltage = 240 V
Cost of energy = N24
To find the cost of running an electric laundry iron;
First of all, we would determine the energy consumption of the iron.
Energy = power * time
Energy = 1200 * 8
Energy = 9600 Watt-hour = 9.6 Kwh (1 Kilowatts is equal to 1000 watts).
Next, we find the cost of energy;
Cost of energy = 9.6 * 24
Cost of energy = N230.4
