Electrical Circuit Safety: Understanding Fuses
How does a fuse protect electrical appliances from excess current?
Which of the following is the appropriate change when a large amount of current flows through the fuse wire connected to the circuit so as to avoid damage of the electrical appliances in the house? 1️⃣ The electric current breaks, as the temperature of the fuse wire rises. 2️⃣ The electric current breaks, as the fuse wire melts. 3️⃣ The temperature of fuse wire decreases. 4️⃣ The direction of current changes due to bending of the fuse wire.
Answer:
A fuse is a safety component that protects electrical appliances from excess current. When a large amount of current flows through the fuse wire, the wire heats up and melts, effectively breaking the circuit and preventing potential damage. So, the correct answer to the question is: 2️⃣
In an electrical circuit, a fuse is a critical safety component that protects electrical appliances from damage due to excess current. When a large amount of current flows through the fuse wire, the wire heats up, eventually melting and breaking the circuit. This is the appropriate change designed to avoid damage to the electrical appliances in the house. So, the correct answer to the question is: 2️⃣ The electric current breaks, as the fuse wire melts.
This action of the fuse wire effectively prevents overheating and potential fires that could be caused by excess current.
