Electrical Circuits

3 of 31

A complete Electrical Circuit is required in order to make electricity practical. Electrons must flow from and return to the power source.

There are three different circuit types, all require the same basic components:

1. Power Source is needed to supply the flow of electrons (electricity).
2. Protection Device prevents damage to the circuit in the event of a short.
3. Load Device converts the electricity into work.
4. Control Device allows the user control to turn the circuit on or off
5. Conductors provide an electrical path to and from the power source.
