- Electrical Energy
- Electrical Power
- Power is measured in watts (W) or kilowatts (kW)
- 1 Watt: Rate of energy transfer equal to 1 joule per second
- 1 Kilowatt: 1000 Watts: 1000 joules per second
- P = E/t
- P - Power in watts
- t - Time taken for the energy to be transferred in seconds
- E - Energy transferred to the appliance in joules
- Power is measured in watts (W) or kilowatts (kW)
- Using Electrical Energy
- The energy transferred to a 1 kW appliance in 1 hour is 1 kilowatt-hour (kWh)
- E = P x t
- P - Power in kilowatts
- t - Time taken for energy to transfer in hours
- E - Energy transferred in kWh
- Electrical Power
