What is the cost of using an electric iron rated 340v, 1000w for 24hrs. If electric energy costs 3000tsh per unit? (1unit=1kwh)

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.
