Why does a fuse blow when too much current flows? 🔥⚡
A fuse is a simple but important circuit-protection device. When excessive current flows through its thin fuse element, heat increases. If the current becomes high enough, the element melts and opens the circuit, stopping the current flow.
Common causes include:
⚡ Overload
🔌 Short circuit
🔥 Excessive current
The fuse sacrifices itself to help protect wiring and electronic components from damage.
**EXCESS CURRENT → HEAT → FUSE MELTS → CIRCUIT PROTECTED**
