Under normal circumstances, how should resistance levels behave in a healthy electrical system?

In a healthy electrical system, resistance levels should remain consistent. This consistency indicates that the components within the system are functioning properly and maintaining their expected characteristics. Fluctuating resistance levels can suggest potential issues like corrosion, overheating, or component failure, which can introduce instability into the system.

A gradual decline in resistance is typically associated with wear and degradation of materials, which is not desirable in a healthy system. Similarly, steadily increasing resistance often indicates that there is an accumulation of oxidation or a failing connection, which could lead to inefficiencies or even failures in the electrical system. Therefore, remaining consistent is the sign of a well-maintained and properly functioning electrical circuit.
