Total cost of electric iron used for 24 hrs is 72000 tsh.
Explanation:
Given
Voltage, V = 340 V
Power, P = 1000 W = 1 kW
Time, T = 24 hrs
Cost per unit = 3000 tsh /unit
Total cost, T = ?
We know,
The cost is calculated in kWh
Therefore,
Total Power consumed = 1 kW X 24 hrs
Total Power consumed = 24 kWh
Total cost = total power X cost per unit
Total cost = 24 kWh X 3000 tsh/unit
Total cost = 72000 tsh
Therefore, total cost of electric iron used for 24 hrs is 72000 tsh.
