4. Volts or voltage Measured using a voltmeter
The push or pressure behind the electrons
Regardless of the number of electgrons
Germany voltage = 220V
U.S. Voltage = 120V

5. Amps or amperage
The number of electrons flowing through a circuit per second
Measured using an ammeter
In the U.S. Max amps is 15.

6. Watts = volts x amps Amount of electrical energy used by a device
Kilowatt hours – the amount of electrical energy used per time
One kilowatt-hour (kWh) is equal to the energy of 1,000 watts working for one hour.
a 60-watt light bulb for 3 hours, you have used 180 watt-hours, or 0.18 kilowatt-hours, of electrical energy.
