Multimeter Usage and Electrical Concepts

This video tutorial explains how to use a multimeter to measure voltage, current, resistance, inductance, and capacitance. It covers the correct use of test leads, understanding multimeter symbols, and settings for different measurements. The video also demonstrates practical examples of measuring voltage and current, using Ohm's Law for calculations, and measuring resistance, capacitance, and inductance. Key concepts include the importance of connecting the multimeter correctly in parallel or series, and understanding the impact of resistance on voltage and current measurements.

Which slot should the black test lead be connected to when using a multimeter?

• The middle slot

• The right slot

• The COM slot

• The left slot

What does the sine wave symbol on a multimeter represent?

• Resistance

• AC voltage

• DC voltage

• Capacitance

Which setting should be used on a multimeter to measure small amounts of current?

• Capacitance setting

• Microamp/milliamp setting

• Resistance setting

• Voltage setting

How should a multimeter be connected to measure voltage across a resistor?

• In parallel with the resistor

• Directly to the power source
