| Question | Answer |
| The most common type of resistor is the _____ resistor. | carbon |
| The carbon resistor is also called the _____ resistor. | fixed |
| The _____ resistor is a type of resistor that can change its resisitance. | variable |
| The variable resistor is also called a _____. | potentiometer |
| ______ are used when varying control of the resistance in a circuit is needed. | Potentiometers |
| The major parts of a potentiometer include a _______, a _______, and a _______. | resistive strip, sliding contact, rotating shaft |
| There are two basic types of potentiometers the ______ and the ______. | linear taper, audio taper |
| In a _______ potentiometer, each increment of shaft rotation corresponds to an equal amount of resistance value. | linear taper |
| In an _______ potentiometer, the resistance varies greatly according to the amount of shaft rotation, especially at the clockwise extreme of rotation. | audio taper |
| ______ potentiometers are often used as volume controls in devices such as TVs and radios. | Audio taper |
| _____ potentiometers are used on circuit boards for temperature, lighting, and motor control circuits. | Miniature |
| The resistance of a miniature potentiometer can be adjusted by turning the _______. | adjustment screw |
| A special type of potentiometer called a _____ is used in some high-power circuits. | rheostat |
| A ____ potentiometer is a wirewound resistor with a sliding tap. The resistance of this resistor can be varied by by loosening the clamp screws and moving the tap to a new spot. | slide |
| The ____ potentiometer is used in power circuits where resistance changes will be made infrequently. | slide |
| The formula _____ states that the amount of power that's actually handled by the resistor is the product of the voltage across the resistor and the current flowing through the resistor. | Power=ExI |
| The color of the first band on the left side end of a resistor tells you the ____ digit in the resistor's value. | first |
| The color of the second band from the left tells you the ____ digit in the resistor's value. | second |
| The color of the third band will tell you how many ____ are placed after the first two digits. | zeros |
| If a resistor has a third band that's gold or silver, it will have a _____ instead of a number of zeros. | multiplier |
| Always read the color bands on a resistor from ____ to ____. | left to right |
| The fourth color band on a resistor tells you the ____ of the resistor as a percentage. | tolerance |
| _____ is the allowable amount of difference between the true resistance and the labeled resistance on a resistor. | Tolerance |
