- Closed Circuit
-
A closed circuit is one in which the pathway of the electrical current is complete and unbroken.
- Open Circuit
-
An open circuit is one in which the pathway of the electrical current is broken.
- Parallel Circuit
-
A parallel circuit has multiple pathways for the current to flow. If the circuit is broken the current may pass through other pathways and other devices will continue to work.
- Series Circuit
-
A series circuit is one which provides a single pathway for the current to flow. If the circuit breaks, all devices using the circuit will fail
