What electrical component is used to protect other circuit components from current overloads?

• A. Diode
• B. Capacitor
• C. Fuse
• D. Resistor

Answer: (C)

A fuse is the component used to protect other circuit components from current overloads. It functions by being designed to carry a specific amount of current safely. When the current exceeds this predetermined threshold, the fuse will heat up and eventually melt, effectively breaking the circuit. This interruption in the flow of electricity prevents excessive current from damaging other components in the circuit, such as transistors, integrated circuits, and other sensitive electronic parts. By removing the current path, a fuse ensures that any potential damage and safety hazards are minimized, which is crucial for maintaining the integrity and reliability of electronic systems.

In contrast, diodes are primarily used to allow current to flow in one direction, capacitors store electrical energy temporarily, and resistors limit the flow of current but do not offer the protective capabilities that a fuse does.
