A resistor is an electrical component that limits or regulates the flow of current in a circuit. Resistors can also provide a specific voltage for active devices like transistors. There are different types of resistors including wire wound, metal film, thick and thin film, surface mount, network, variable, and light-dependent resistors.

1. WHAT IS A RESISTOR?
A resistor is an electrical component that
limits or regulates the flow of electrical
current in an electronic
circuit. Resistors can also be used to
provide a specific voltage for an active
device such as a transistor.
