Answer
One "unit" of electricity, also called a kilowatt-hour (kWh), euals 1000 watts used for 1 hour. This is the standard measurement used by utility companies to bill for electricity consumption. For example:
- A 100-watt bulb running for 10 hours = 1 kWh (1 unit)
- A 1000-watt (1 kW) appliance running for 1 hour = 1 kWh (1 unit)
- A 500-watt device running for 2 hours = 1 kWh (1 unit)
Understanding units helps you calculate electricity costs and manage energy consumption effectively.
