Electric Fuse wire is working on principle.
Electric Fuse wire is working on principle.
- A. control of voltage in circuit
- B. chemical effect of electric current
- C. control of current in circuit
- D. heating effect of electric current
Step-by-step solution
A fuse wire is designed with a low melting point. When current exceeds a safe limit, the wire heats up due to Joule heating (I²R) and melts, breaking the circuit to prevent damage. This operation relies on the heating effect of electric current, not voltage control, chemical effects, or current control alone.
