How to Measure Voltage with a Multimeter

The video tutorial explains how to use a multimeter to measure voltage. It starts with setting up the multimeter by connecting the black probe to the COM port and the red probe to the V port. The tutorial then guides viewers on selecting the appropriate DC voltage setting, suggesting 20 volts for small battery-powered circuits. Finally, it demonstrates how to measure voltage by connecting probes in parallel to the component being tested, such as an LED, and explains how to interpret the readings, including the effect of reversing the probes.

Where should the black probe be connected on a multimeter?

• Port labeled Ω

• Port labeled A

• Port labeled COM

• Port labeled V

What symbol indicates a DC voltage setting on a multimeter?

• A V with a circle

• A V with a straight and dashed line

• A V with a triangle

• A V with a wavy line

What is a recommended starting voltage setting for small battery-powered circuits?

• 10 volts

• 15 volts

• 20 volts

• 25 volts

How should the probes be connected to measure voltage across a component?

• In series with the component

• In parallel to the component

• Directly to the power source

• In a loop with the component

What happens if you reverse the probes while measuring voltage?

• The multimeter will not work

• The multimeter will show zero

• The multimeter will show a negative voltage

• The multimeter will show a positive voltage
