CIRCUIT
Definition
a path for current to flow in a continuous loop, usually including a power source,
wires, and a load such as lamps, motors and so on
Term
SERIES CIRCUIT
Definition
a circuit in which all the current flows in a single path through every
component in succession.
Term
CLOSED CIRCUIT
Definition
a conductor arranged in a continuous loop in which current can flow
Term
OPEN CIRCUIT
Definition
circuit which has been broken, preventing current from flowing
Term
SHORT CIRCUIT
Definition
A circuit with a very low-resistance path that shunts current directly
across the power source. An unintended shorter path for current.
