प्रश्न
My mother was operating washing machine on Sunday morning. Suddenly, she saw a spark coming out of the electric board and the electric current in the house failed. An electrician was called to look into the matter. What should he have noticed.
उत्तर
- When electrician was called, he checked circuit and found that circuit catches fire due to short circuit.
- He observed that live wire and neutral wire came in direct contact which resulted in short circuit.
- Because short circuit resistance of the circuit becomes very small and hence huge amount of current flows through it.
- It ultimately produces a large amount of heat and raises the temperature. As a result circuit catches fire.
