Energy & Power
- Power is defined as the energy transferred per second
- Power is measured in watts
- Since power is energy transferred per second, the watt can also be defined as 1 joule per second
1 W = 1 J / s
- 1 kilowatt (1 kW) is equal to 1000 watts, or 1000 joules of energy transferred per second (1 kJ / s)
