Resistor

Resistors "resist" the flow of electricity and are used to control or limit the electricity in a circuit. Snap Circuits includes 100 ohm (R1), 1K ohm (R2), 5.1K ohm (R3), 10K ohm (R4), and 100K ohm (R5) resistors ("K" symbolizes 1,000, so R3 is 5,100 ohm). Materials like metal haver very low resistance (<1 ohm) and are called conductors, while materials like paper, plastic and air have near-infinite resistance and are called insulators.
