Given - Voltage - 220 V

Power - 2kW

Time - 3 hour

Cost per kWh - ₹ 4.25

Find - Cost of running an electric iron for one week for given duration.

Solution - Energy consumption of electric iron per day as per given values - Power*time.

Energy consumption - 2*3

Energy consumption - 6kWh

Energy consumption for a week - 6*7

Energy consumption - 42 kWh.

Total cost - Cost per kWh * total number of kWh.

Total cost - 4.25*42

Total cost - Rs. 178.5

Hence, total cost of running an electric iron for a week for given duration of time is Rs. 178.5.
