Transformer | a machine that changes the voltage of an alternation current without losing much energy |
Alternating current | a current that changes direction. The voltage can speed up or slow down. |
Direct current | current where electrons flow in one direction |
Series Circuit | has one path for the flow of electric current. If the path is broken the current cannot flow. |
