Exam 3: Resistors

Two major characteristics of a resistor are

A device that is used to provide any one resistance within a wide range of values is a

What type of resistor is typically used as a precision resistor?

What type resistor is formed by spraying a thin film of metal onto a ceramic substrate and then cut in the form of a spiral?

Resistors have a relatively short shelf life and only keep their characteristics for six to eight months.

The amount by which the actual resistance can differ from the color-coded value is the:

A resistor is used to

What is indicated when a volume or tone control makes a scratchy noise as the shaft is rotated?

What type of resistor is constructed by wrapping resistance wire around an insulating core?

Rheostats and potentiometers are referred to as

A potentiometer can never be wired as a rheostat.

______________-mount resistors are constructed by depositing a thick carbon film on a ceramic base.

A resistor that is color-coded red, green, red has a value of 2500 ohms.

Variable resistors can be wire-wound or

A resistor whose resistance value changes with changes in operating temperature is a

As measured with an ohmmeter, infinite ohms means

Zero-ohm resistors are commonly found on printed circuit boards.

A resistor with a single black band around the center of the resistor body has a resistance of

For ambient temperatures greater than 70°C, the power rating of a resistor must be

Commercial rheostats are typically
