A circuit in which current follows more than one path. Each device that is wired in a parallel circuit has its own path to and from the voltage source.
parallel circuit
A closed path through which charge can flow.
circuit
An electrical device that slows the flow of charge in a circuit.
resistor
A circuit in which current flows a single path. Each device that is wired in a series circuit shares a path to and from the voltage source.
series circuit
An unintended and undesired path connecting one part of a circuit with another.
short circuit
