Lab 14 Electricity Bill Worksheet Background knowledge. The power of an electrical appliance is measured in watt (W). One watt is a measure of the energy used up in one second. The unit used for calculating power consumption is the kilowatt-hour (kWh). In order to calculate power consumed by an electrical appliance, we first convert the power to kilowatt (kW). For example, 800 W=0.8 kW, 2000 W = 2.0 kW and so on. One unit...

2. Many electronic devices use electricity even when they are turned off. Old CRT televisions were notorious "energy vampires", some using 10 W of power when off. Newer flat panel TVs are much more efficient. How much would an old CRT TV cost you in electricity if it were plugged in (but left off) for a year. Assume it uses 10 W of power continuously and that electricity costs $0.10 per kWh. nologies
