A fuse operates similarly to a circuit breaker, serving to prevent home circuits from overloading. It incorporates a resistance wire with a low melting point, connected in series within a circuit. When the total current in the circuit surpasses its maximum capacity, the fuse wire, designed with a specific melting point, heats up and melts. This deliberate melting breaks the circuit, preventing overloading and potential hazards. Fuses are available with varying melting points to accommodate different current strengths in home electrical circuits.
