Multimeter Basics Flashcard

Front

What is a multimeter?

Back

A multimeter is an electronic measuring instrument that combines several measurement functions in one unit, including voltage, current, and resistance.

Front

How do you measure voltage with a multimeter?

Back

To measure voltage, set the multimeter to the voltage setting, connect the probes across the component, and read the value on the display.

Front

What is the function of an ohmmeter?

Back

An ohmmeter measures the resistance of a component or circuit.

Front

What safety precaution should be taken when using a multimeter?

Back

Always ensure the multimeter is set to the correct measurement type and range before connecting it to a circuit.

Front

What does it mean to measure continuity?

Back

Measuring continuity checks if there is a complete path for current to flow in a circuit.

Front

How should you connect an ohmmeter to a circuit?

Back

An ohmmeter should be connected in parallel and the circuit should be powered off.

Front

What is the purpose of measuring resistance in a circuit?

Back

To determine the opposition to the flow of electric current.

Front

When measuring an unknown voltage, how should you set the multimeter?

Back

Set the multimeter to the highest voltage setting to avoid damage.

Front

What is the difference between AC and DC voltage?

Back

AC (Alternating Current) voltage changes direction periodically, while DC (Direct Current) voltage flows in one direction.

Front

What is the significance of the lowest setting on a multimeter?

Back

The lowest setting allows for more accurate measurements of small voltages or resistances.
