Question 1

What type of&#160;resistors are generally used when a high power rating is needed?&#10;A) carbon film&#10;B) metal glaze&#10;C) wire-wound&#10;D) &#8203;metal film

Accepted Answer

Wire-wound resistors are generally used when a high power rating is needed because they are able to handle a larger amount of power than other types of resistors. They are made by winding a resistive wire around a ceramic or fiberglass core, and the wire material and thickness can be chosen to handle a wide range of power ratings. Carbon film, metal glaze, and metal film resistors are not as well-suited for high power applications.

Question 2

Resistors functioning as _____ are used in applications involving field-effect transistors (FETs) and multirange voltmeter circuits.&#10;A) voltage dividers&#10;B) current dividers&#10;C) voltage multipliers&#10;D) current multipliers

Accepted Answer

Resistors functioning as voltage dividers are commonly used in applications involving FETs and multirange voltmeter circuits to vary the output voltage. Current dividers are used to split a current into multiple paths, while voltage multipliers and current multipliers are used to increase the voltage or current respectively.

Question 3

A variable resistor with two terminals is called a _____.&#10;A) multiturn resistor&#10;B) potentiometer&#10;C) wire wound resistor&#10;D) rheostat

Accepted Answer

A variable resistor with two terminals is called a rheostat. A potentiometer also has three terminals and is used as a voltage divider, while a wire-wound resistor and multiturn resistor can have more than two terminals.

Question 4

A resistor whose values can be varied over a range of values is called a _____ resistor.&#10;A) fixed&#10;B) variable&#10;C) carbon&#10;D) wire wound

Accepted Answer

A variable resistor, also known as a potentiometer, is designed to have a range of values that can be adjusted manually. Fixed resistors have a set value, while carbon and wire wound refer to the materials used to construct resistors and do not indicate a variable value.

Question 5

The value of a resistor can often be determined by the &#34;color code.&#34;

Accepted Answer

The color code on a resistor provides information on its resistance value, tolerance, and sometimes its wattage rating, allowing one to determine the value of the resistor.

Question 6

How many color bands are used on resistors that have&#160;a tolerance of &#177;20 percent?&#10;A) three&#10;B) four&#10;C) five&#10;D) six

Accepted Answer

Resistors with a tolerance of ±20 percent typically use three color bands to indicate their resistance value. The first two bands represent the significant digits, and the third band represents the multiplier. The tolerance is not explicitly marked by a band in this case, as ±20% is considered the default tolerance when no tolerance band is present.

Question 7

There is very little resistance and a large amount of current flows in a(n) _____ circuit.&#10;A) open&#10;B) long&#10;C) short&#10;D) closed

Accepted Answer

A short circuit occurs when there is a low resistance connection between two conductors supplying electrical power to a circuit. This results in an excessive amount of current flowing into the circuit, potentially causing circuit damage, overheating, fire or explosion.

Question 8

What type of fixed resistor is made by winding a piece of resistive wire around a ceramic core?&#10;A) carbon film&#10;B) metal film&#10;C) metal glaze&#10;D) wire-wound

Accepted Answer

Wire-wound resistors are made by winding a resistive wire around a ceramic core. This design allows for higher power ratings and greater precision compared to other types of fixed resistors, such as carbon film, metal film, and metal glaze resistors. Therefore, the best choice is D – wire-wound.

Question 10

What type of resistor operates by moving the wiper arm with a screw of some number of turns?&#10;A) pot&#10;B) wire-wound&#10;C) multiturn variable&#10;D) rheostat

Accepted Answer

The question describes a multiturn variable resistor, also known as a potentiometer or pot. A wire-wound resistor has a coiled wire as the resistive element and does not have a moving wiper arm. A rheostat is a type of variable resistor with only two connection points and is used to regulate current, not voltage.
