Final answer:
To calculate the electrical consumption expenses of an electric iron used for 2 hours daily, multiply the usage in kilowatt-hours by the cost per unit. For April, the cost would be Rs 330.
Step-by-step explanation:
To calculate the electrical consumption expenses for operating an electric iron that consumes 1100 watts (W) over the month of April, we can use the formula:
Energy Usage (kWh) = Power (kW) × Time (hours)
Cost = Energy Usage × Rate per Unit
Firstly, we convert the power from watts to kilowatts (1 kW = 1000 W):
1100 W = 1.1 kW
Next, we calculate the total operating time for April. Assuming April has 30 days, the iron is used for 2 hours each day:
Total Time = 2 hours/day × 30 days = 60 hours
Now, calculate the total energy consumption:
Energy Usage = 1.1 kW × 60 hours = 66 kWh
Finally, calculate the cost using the rate provided by the electric company, which is Rs 5 per unit (kWh):
Cost = 66 kWh × Rs 5/kWh = Rs 330
Therefore, the electrical consumption expenses for using the electric iron in April would be Rs 330.
