Direct Current (DC)
- When charges particles in a circuit travel in only one direction
- The current from a cell is called direct current
- Electrons move from the negative terminal to the positive terminal
Alternating Current (AC)
- Electrons move back and forth, but there is no net movement of electrons in either direction
- Magnet and coil of wire
- A simple electrical device that can change the potential difference of an alternating current
- e.g. when you plug in a cellphone into a wall outlet, a transformer reduces the potential difference from 110 volts to the amount needed
- Transformers do not work with DC
Circuit Breaker And Fuse
Both are safety devices that are placed in series with other circuits which lead to the appliances and wall outlets.
