Book Free DemoA 100 \(watt\) electric bulb is used for 5 \(hours\) daily and four 60 \(watt\) bulbs are used for 5 \(hours\) daily. Calculate the energy consumed in the units of \(kWh\) in the month of January.
[Note: Enter the answer up to two decimal places by rounding off the third decimal value].
The formula for electrical energy is
Energy used by 100 \(watt\) bulb is \(Wh\).
Energy used by four 60 \(watt\) bulb is \(Wh\).
Hence, the total energy used per day,
On converting \(Wh\) to \(kWh\), we get \(kWh\).
Number of days in January \(=\) 31 days
Energy used in January
Thus, the energy consumed by the bulbs in the month of January is \(kWh\).
