What electrical quantities can a multimeter measure?

• Current, voltage, and power

• Current, voltage, and resistance

• Voltage, resistance, and frequency

• Current, power, and frequency

What is a key difference in operation between an analog multimeter and a digital multimeter?

• Analog multimeters are more accurate than digital multimeters.

• Digital multimeters require manual calculation of measurement values.

• Analog multimeters require careful selection of measurement range and scale interpretation, while digital multimeters simplify this.

• Digital multimeters can only measure AC quantities, while analog can measure both AC and DC.

When measuring DC current with a multimeter, what is a crucial consideration regarding the measurement range?

• The selected range should always be the lowest possible to ensure accuracy.

• The multimeter's measurement capability must be lower than the expected current to prevent damage.

• The selected range should be higher than the estimated current to avoid damaging the multimeter.

• The range selection is only important for AC current measurements, not DC.

If an analog multimeter is set to a 2.5V range and the needle points to 170 on the 250 scale, what is the measured DC voltage?

• 170 V

• 17 V

• 1.7 V

• 0.17 V

What is a crucial step to perform before measuring resistance with an analog multimeter to ensure accurate readings?

• Set the multimeter to the highest possible resistance range.

• Connect the probes to the circuit and then adjust the zero.

• Touch the red and black probes together and adjust the ohm adjustment knob until the needle points to zero.

• Ensure the multimeter is connected to a power source.
