Answer :
Final answer:
Fuses and circuit breakers are vital symbols in control schematics, acting as safety devices to prevent electrical hazards by interrupting circuits when overloaded.
Explanation:
Fuse and circuit breakers are commonly used symbols in control schematics. Fuses consist of a metal strip with a low melting point that breaks the circuit in case of excessive current, while circuit breakers are automatic switches that open the circuit when needed.
- A fuse is a safety device that interrupts the circuit when overloaded.
- Circuit breakers provide the advantage of easy restoration after tripping due to excess current.
- Both fuses and circuit breakers play crucial roles in preventing electrical hazards in circuits.
