Describe the ways a resistor can be identified.
Base Color code, Axial Color code, Part Number, Direct Measure
What are some types of variable resistors?
Photo resistors, Potentiometers, Thermistors etc.
What is the purpose of a resistor in a circuit?
The purpose of a resistor in a circuit is to control the flow of electric current, limit voltage, divide voltage, or dissipate power.
In the four color band system of resistor identification, what is the third color band represent?
The multiplier.
What is meant by the term tolerance as it refers to the fourth color band?
The allowable variation in resistance from the stated value.
