| Approximate Wattage Requirements For Common Appliances | |||||||||||
| Useful Definitions: | |||||||||||
| Volts = Electric potential, similar to pressure in water systems | |||||||||||
| Amps = Electric current flow, similar to gallons per min. in water systems. | |||||||||||
| Watts = Rate of energy production or consumption = volts x amps, similar to speed (rate of movement; miles per hour) | |||||||||||
| Watt-hours = Total power produced or consumed = watts x hours | |||||||||||
| Kilowatt = 1000 watts; 1 kilowatt-hour (1kWh)= 1000 watt hours | |||||||||||
| AC = Alternating Current; electrical energy form, as is available form mains, generators and inverters. | |||||||||||
| DC = Direct Current; electrical energy form as is stored in batteries. | |||||||||||
