Resistance Part Two: Base Electronics: 6

This lesson covers practical aspects of resistors, including schematic symbols, color coding, and power ratings. It explains how resistors are represented in schematics, how to read their values using color bands, and the importance of power ratings. The lesson emphasizes the need to choose appropriate power ratings to prevent circuit damage and concludes with a review of key points.

What is the most common schematic symbol for a resistor?

• A triangle

• A circle

• A zigzag line

• A straight line

How is a resistance value of 10,000 ohms commonly represented?

• 10G

• 10m

• 10M

• 10k

What does the third band on a resistor indicate?

• The number of zeros to add

• The second digit of the resistance value

• The tolerance

• The first digit of the resistance value

What does a tolerance of 1% on a resistor mean?

• The resistor's value is fixed

• The resistor's value can vary by 0.1%

• The resistor's value can vary by 1%

• The resistor's value can vary by 10%

What is the unit of measurement for power in resistors?

• Ohms

• Volts

• Watts

• Amps

If a resistor is consuming 0.06 watts, what is the minimum power rating you should choose?

• 0.03 watts

• 0.06 watts

• 0.12 watts

• 0.125 watts

Why is it important not to exceed a resistor's power rating?

• It will cause the resistor to burn out

• It will decrease the resistance

• It will make the resistor more efficient

• It will increase the resistance
