What is the tolerance of a Precision Resistor?

• A. 5% or less
• B. 10% or less
• C. 1% or less
• D. 0.5% or less

Answer: (C)

Precision resistors are designed to have a very tight tolerance that allows for greater accuracy and reliability in electronic circuits. A tolerance of 1% or less indicates that the actual resistance value is guaranteed to be within 1% of its nominal value. This high level of precision is crucial in many applications, particularly in sensitive electronic instruments, where even small deviations in resistance can lead to significant errors in performance. Consequently, the correct answer reflects the typical specification for precision resistors, setting them apart from general-purpose resistors which may have wider tolerances. The options focused on tolerances greater than 1% do not meet the criteria for precision, as they allow for larger variations in resistance that would not be acceptable in applications requiring high accuracy.
