What is an electrical drawing that indicates how components are grouped together to form stages called?

Back

A block diagram.

Front

What can be added to a circuit to extend the range of a voltmeter?

Back

Multiplier resistors can be added to extend the range of a voltmeter.

Front

What is the name of an electrical drawing that indicates the location of each component in a circuit and the value of each?

Back

A schematic diagram.

Front

What is the primary function of a voltmeter?

Back

The primary function of a voltmeter is to measure the voltage (electrical pressure) in a circuit.

Front

What does VOM stand for in electrical measurements?

Back

VOM stands for Volt-Ohm-Meter.

Front

What type of diagram is used to represent the flow of electricity in a circuit?

Back

A schematic diagram is used to represent the flow of electricity in a circuit.

What is the purpose of multiplier resistors in a voltmeter circuit?

Back

Multiplier resistors are used to extend the measurement range of a voltmeter.

Front

What is the difference between a block diagram and a schematic diagram?

Back

A block diagram shows how components are grouped together, while a schematic diagram shows the actual connections and values of components.
