Using Multimeters: Voltage, Current, and Resistance…

Q: What unit is used to measure voltage?

Volts (V) — Voltage is measured in Volts (V), representing electrical potential difference.

Q: Which setting on a multimeter is used to measure current?

Amperage (A) — Current is measured using the Amperage (A) setting.

Q: What unit is used to measure resistance?

Ohms (?) — Resistance is measured in Ohms (?), representing the opposition to current flow.

Q: When measuring voltage, the multimeter probes should be connected in:

Parallel — Voltage is measured across a component, requiring a parallel connection.

Q: When measuring current, the multimeter probes should be connected in:

Series — Current must flow through the meter, requiring a series connection.

Q: Before measuring resistance, you should:

Disconnect the component from the circuit. — Resistance measurement requires the component to be isolated from any power source.

Q: What is the purpose of the continuity setting on a multimeter?

To check if a circuit is complete (a path exists). — Continuity checks for a complete, unbroken circuit path.

Q: What could happen if you try to measure voltage while the multimeter is set to measure current?

The multimeter will be damaged. — Trying to measure voltage while set to current can damage the meter due to the low impedance setting.

Q: Which probe is typically red on a multimeter?

Positive probe — The red probe is typically connected to the positive terminal.

Q: Which setting should you use to check if a fuse is good?

Resistance (low range) or Continuity — A good fuse will show very low resistance or indicate continuity.
