Max and Min Resistance Value

What is the correct order of color bands in a 4-band resistor?

• Tolerance - Multiplier - 2nd Digit - 1st Digit

• 1st Digit - 2nd Digit - Multiplier - Tolerance

• Multiplier - Tolerance - 1st Digit - 2nd Digit

• 2nd Digit - 1st Digit - Multiplier - Tolerance

If a resistor has the color bands Red - Red - Brown - Gold, what is its resistance value?

• 22Ω

• 220Ω

• 2200Ω (2.2kΩ)

• 22000Ω (22kΩ)

What is the tolerance value of a resistor with a silver band?

• ±5%

• ±10%

• ±20%

• ±2%

How do you convert a 5% tolerance into decimal form?

• 5.0

• 0.5

• 0.05

A resistor has a nominal value of 1,000Ω and a tolerance of ±10%. What is the maximum possible resistance?

• 900Ω

• 1,100Ω

• 990Ω

• 1,010Ω

A resistor has a resistance of 470Ω with a ±5% tolerance. What is the minimum possible resistance?

• 423.5Ω

• 446.5Ω

• 450Ω

• 500Ω

What happens if a resistor with a lower tolerance is used instead of the correct one?

• The circuit will work more efficiently.

• The resistance value will remain the same.

• The circuit may experience unstable operation.

• The resistor will increase the power supply voltage.

What is the purpose of the multiplier band in a resistor?

• It determines how much to multiply the first two digits by.

• It tells the resistor's power rating.

• It represents the percentage tolerance.

• It indicates the temperature coefficient.

If a resistor has a resistance value of 2,200Ω and a ±5% tolerance, what is its resistance range?

• 2,090Ω - 2,310Ω

• 2,150Ω - 2,250Ω

• 2,000Ω - 2,400Ω

• 2,100Ω - 2,350Ω

Why is it important to calculate the maximum and minimum resistance values of a resistor?

• To determine if the resistor will function within a circuit's safe limits.

• To make the resistor look more professional.

• To increase the voltage supply.

• To change the color bands on the resistor.
