Electrical

energy

​

The rate of flow of electric charges (per second)​

Unit: ​•amperes, “amps", A.

​

The direction of current and electron movement

​

• charges always flow in the same direction.

• Generated by battery​

• current alternates direction

• Generated by powerplant​

​

• Resistance: The opposition to the flow of electric charge. Unit: ohms, Ω
