How does high resistance in an electrical circuit affect the system?

High resistance in an electrical circuit can indeed lead to overheating. When resistance is high, it impedes the flow of current, which can cause the electrical components to work harder to push current through. As a result, energy is dissipated in the form of heat. This overheating can damage components, create fire hazards, and lead to circuit failure.

While high resistance does affect the amount of current flowing (usually resulting in lower current), the immediate concern in terms of safety and equipment integrity is the heat generated from the increased resistance. This is why understanding the implications of high resistance is critical in maintaining safe and effective electrical systems.
