Q

Series circuit.

A

A circuit in which all current flows through the same path. By adding loads or resistors in a series circuit, the flow of current is decreased.

Q

Resistor

A

Resisters oppose the flow of electrical current within a circuit. The amount of resistance a resistor can have can vary depending on the resistor. A resistor’s resistance can be found by the colored bands of a resistor.
