• To repair electrical circuits

• To measure voltage, current, and resistance

• To measure electrical current only

What should be removed from the multimeter leads before taking measurements?

• The batteries

• The dust covers

• The LCD screen

• The range switch

What symbol represents the continuity function on a multimeter?

• A lightning bolt

• A sideways Wi-Fi symbol

• A plus sign

• An omega symbol

What must be done to a device before measuring continuity?

• It must be powered on

• It must be fully charged

• It must be unplugged or turned off

• It must be connected to a computer

What does a continuity test tell you?

• The amount of power a device uses

• If there is a connection between two points

• The exact voltage of a circuit

• How much resistance is in a circuit

How is resistance measured in a circuit?

• In amps

• In volts

• In ohms

• In watts

What is the significance of the omega symbol on a multimeter?

• It shows the battery level
