Question

An electric iron of 600 W is operated for 1 hrs daily. What will be the electrical consumption expenses for that in the month of April? (The electric company charges Rs 8 per unit of energy).

Answer 1

Sure, here is the complete solution with the given information, calculation steps, and final answer:

Given:

• Power of electric iron = 600 W
• Time electric iron is operated daily = 1 hour = 3600 seconds
• Rate of energy by the electric company = Rs 8 per unit

To find:

• Electrical consumption expenses for the electric iron in the month of April

Solution:

1. Calculate energy consumption in one day: Energy consumption in one day = Power x Time = 600 W x 3600 s = 2,160,000 J

2. Calculate energy consumption in April: Energy consumption in April = Energy consumption in one day x number of days in April = 2,160,000 J/day x 30 days = 64,800,000 J

3. Calculate number of units consumed: Number of units consumed = Energy consumed / energy per unit = 64,800,000 J / (3.6 x 10^6 J/unit) = 18 units

4. Calculate total cost: Total cost = Number of units consumed x rate per unit = 18 units x Rs 8/unit = Rs 144

Therefore, the electrical consumption expenses for the electric iron in the month of April will be Rs 144.

Answer 2

The electric consumption for the iron in one day is:

Energy consumption in 1 hour = Power x Time Energy consumption in 1 hour = 600 W x 1 h = 600 Wh

As the iron is operated for 1 hour daily, the energy consumption in one day will be 600 Wh.

Energy consumption in one month (April) = Energy consumption in one day x Number of days in April Energy consumption in one month = 600 Wh/day x 30 days = 18,000 Wh

To calculate the electricity bill, we need to convert the energy consumption from watt-hours (Wh) to kilowatt-hours (kWh).

Energy consumption in one month = 18,000 Wh = 18,000/1000 kWh = 18 kWh

Now we can calculate the electricity bill using the rate of Rs 8 per unit of energy:

Electricity bill = Energy consumption x Rate per unit Electricity bill = 18 kWh x Rs 8/kWh = Rs 144

Therefore, the electrical consumption expenses for the electric iron in the month of April will be Rs 144.
