what happens inside an electrical connection.
Every power strip has a maximum electrical rating. This rating indicates the amount of electrical current or power the device is designed to handle under specified conditions.
When connected appliances demand more current than the strip can safely carry, its internal components may heat up.
Electrical resistance plays an important role. Even a small amount of resistance in a poor connection can generate heat when current flows through it.
The relationship is described by Joule’s law:
Heat generated = Current² × Resistance × Time
This explains why
