RESISTORS AND MULTIMETERS

You have a resistor with the following color bands: Brown, Black, Red, and Gold. What is the resistance value of this resistor?

• a) 1.0 Ω with ±5% tolerance

• b) 10 kΩ with ±5% tolerance

• c) 1 kΩ with ±5% tolerance

• d) 100 Ω with ±10% tolerance

What is the purpose of the gold or silver band on a resistor?

• a) Indicates the power rating of the resistor.

• b) Represents the tolerance percentage.

• c) Shows the temperature coefficient of the resistor.

• d) Specifies the resistor's manufacturer.

What is the value of the resistor?

• a) 210Ω ±10%

• b) 21 Ω ±10%

• c) 2.1 Ω ±10%

• b) 21000Ω ±10%

What is the primary function of a multimeter in measuring resistors?

• a) Measure temperature changes in the resistor.

• b) Measure the voltage drop across the resistor.

• c) Determine the resistance value in ohms.

• d) Measure the current flowing through the resistor.

You set the multimeter to resistance mode and connect the probes to a resistor. The display reads "1." What does this indicate?

• a) The resistor has a value of 1 Ω.

• b) The resistor is functioning properly.

• c) The resistor's value exceeds the multimeter's range.

• d) There is no connection between the probes and the resistor.
