Question

  1. if it were desirable to use a resistor that did not change its resistance value over time, a metal-film resistor would be a good choice.

true

false

Explanation:

Analyze the properties of metal-film resistors

Metal-film resistors are constructed by depositing a thin layer of metal onto a ceramic substrate. This manufacturing process gives them excellent long-term stability, low noise, and a very low temperature coefficient of resistance compared to carbon composition resistors.

Evaluate resistance stability over time

Because of their construction, metal-film resistors experience minimal aging effects and maintain a highly stable resistance value over long periods of operation. Therefore, if a circuit requires a resistor that does not change its resistance value over time, a metal-film resistor is indeed an excellent choice.

Answer:

  • True (Correct answer)
  • False
