\nTo calculate the energy consumed, we use the formula: Energy = Power \u00d7 Time.
\nPower = 100 W = 0.1 kW (kilowatt).
\nThe bulb is used for 8 hours per day.
\nThe month of April has 30 days.
\nTotal usage time in April = 8 hours\/day \u00d7 30 days = 240 hours.
\nEnergy consumed in kWh = Power (kW) \u00d7 Total time (hours) = 0.1 kW \u00d7 240 hours = 24 kWh.
\nOne unit of electrical energy is equivalent to 1 kWh.
\nTherefore, the energy consumed is 24 units.
\n<\/section>\n
\n– Convert power from Watts to Kilowatts (1 kW = 1000 W).
\n– Calculate the total usage time in hours for the month.
\n– Use the formula: Energy (kWh) = Power (kW) \u00d7 Time (hours).
\n– 1 unit of energy = 1 kWh.
\n<\/section>\n
\nElectrical energy consumption is typically measured in kilowatt-hours (kWh) by electricity meters. This unit is often referred to as a “unit” in common parlance for billing purposes.
