Quiz on Electrical Measurements

To measure the voltage in an electrical circuit, the most suitable tool to use is:

• Amperemeter

• Ohmmeter

• Voltmeter

• Thermometer

An electrical circuit consists of a battery, resistor, and connecting wires. The way to use a multimeter to measure the current flowing in the circuit is....

• Connect the multimeter in parallel with the resistor and set it to voltage measurement mode.

• Connect the multimeter in series with the circuit and set it to current measurement mode.

• Connect the multimeter in parallel with the battery and set it to current measurement mode.

• Connect the multimeter in series with the circuit and set it to voltage measurement mode.

The first step in using a multimeter to measure the resistance of a resistor is:

• Connect the multimeter in series with the resistor

• Set the multimeter to resistance measurement mode

• Connect the multimeter to a voltage source

• Set the multimeter to voltage measurement mode

To measure the voltage in an electrical circuit, you must connect the multimeter....

• In series with the component

• In parallel with the component

• Diagonally with the component

• Without connecting it directly

A student wants to find out how much voltage is in a battery. What should be done with the multimeter is....

• Set to voltage measurement mode and connect in parallel with the battery

• Set to current measurement mode and connect in series with the battery

• Set to resistance measurement mode and connect in series with the battery

• Connect directly without setting the mode

In testing an electrical circuit, if the multimeter shows a negative voltage value, what should be done is....

• Reverse the connection poles on the multimeter

• Check for damage in the circuit

• Replace the measuring instrument used

• Re-measure without changing anything

A resistor has a value of 100 Ω. What happens if the current passing through the resistor exceeds its limit is....

• The resistor will generate higher power

• The resistor may burn

• The resistor will become cold

• There will be no change

The following tool used to convert AC voltage to DC voltage is....

• Transformer

• Capacitor

• Resistor

• Rectifier

You are asked to measure the power of an electrical device connected to an AC voltage source. What is the first step to take with the multimeter?

• Connect the multimeter in parallel with the device

• Set the multimeter to current measurement mode

• Set the multimeter to power measurement mode

• Ensure the multimeter has a sufficient scale for voltage

In the process of testing electrical cables, high resistance in the cable usually indicates:

• The cable is in good condition

• The cable has insulation damage

• The cable has a damaged or broken core

• The cable is experiencing a short circuit
