| Direct Current (DC) | what you get from things like batteries, fuel cells and solar cells, the flow of electricity always does in one direction |
| Alternating Current (AC) | comes from our walls, the current flows in one direction and then switches and flows the other way, it alternates back and forth |
| Power Plants | where electrical energy is made |
| Generators | change mechanical energy to electrical energy to make alternating current |
| Transformer | where voltage is increased so it can travel across long distances and not lose much energy |
| Transmission Wires | the high voltage alternating current runs along these, some are above ground while others are underground |
| Allesandro Volta | Volts are named after him, he made an early battery |
| Michael Faraday | discovered that if you loop wire into a coil and move a magnet through it, it generates an electric current |
