5 Concepts on Fuse that Every Power Protection Beginner Should Know

Simplest Form of Fuse [MCQ]

1. A simple wire

Explanation: The simplest form of fuse is a simple wire which connects in series with the circuit and protects it.

1. Series

Explanation: A fuse always conects in series to circuit. Its reason is that on fault it should make an open circuit.

In case of parallel it would create a short (partial or metallic) and can damage the circuit.

2. Low Melting Point

Explanation: Mostly a low metling point is desired so that it should melt and not allow excessive current to flow through it.

No, we have very large sized Fuses that are also connected with power systems. An example of 115 kV Fuse is shown below.

An application of Fuse is in the Laptop charger which uses a fuse in the plug for proectection against a current higher than rated current.
