Question

Identify the figure and explain their use.
​

Answer 1

a))Function Of Fuse

• Acts as a barrier between the electric circuit and the human body
• Prevents device failure due to faulty circuit operation
• Fuse prevents short-circuits
• Prevents overload and blackouts
• Prevents damage that is caused due to mismatched loads

b))MCB has several advantages over fuse:

• MCB is more sensitive to current than fuse.
• In case of MCB, the faulty zone of electrical circuit can be easily identified.
• With MCB it is very simple to resume to the supply.
• MCB provides a better interface with the help of knob than a fuse.
• Handling MCB is electrically safer than handling a fuse.

Answer 2

Answer:

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
