How to calculate energy?
Energy refers to the capacity to do work. The formula for electrical energy is as follows:
Energy = Power x Time
Where:

Power is typically given in Watts (like a light bulb)
Time is usually given in seconds
Energy is usually measured in joules.

According to this question, Nicholas spends 20 minutes ironing shirts with his 1,800-watt iron. The energy used by the iron can be calculated as follows:
Energy = 1800watts × 1200s = 2.16 × 1 0 6 J
