How is electric energy consumption calculated?
Electric energy consumption is calculated using the formula E=P×t, where P is the power in watts and t is the time in hours. The result is typically measured in kilowatt-hours (kWh).
How is electric power measured in household appliances?
The power rating of household appliances is usually mentioned on a label in watts or kilowatts. It indicates how much power the device consumes when operating at its rated voltage.
