Electrical energy can be calculated using which of the following formulas?
Energy = Power × Time
Electrical energy is calculated using the formula Energy = Power × Time, since power is the rate of energy transfer.
Energy = Power ÷ Time, Energy = Voltage × Current, and Energy = Current × Resistance do not correctly represent the relationship between energy and power.
Hence, 'Energy = Power × Time' is the correct answer.
