Jeremy has a handful of resistors. all of them, except one, have four bands. the exception has three. why? a. he should use another because the band may haven't been printed or worn out, and using the resistor could damage the circuit since there's no way to tell its value due to the missing band. b. the resistor has a tolerance of 20%. c. the resistor has a non-decimal value, like 10 ohms, instead of 10.4 ohms. d. the resistor has a low resistance value so it properly only has three bands.

option B: The resistor has a tolerance of 20%.

Explanation:

Resistors are color coded to identify their value and function. For a 3- Band resistor, reading from the left, first band denotes first digit, second band depicts second digit and third color depicts the multiplier. The absence of fourth band means the resistor has tolerance 20%.

Hence, the correct answer is option B. The resistor has a tolerance of 20%.
