Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the ...

It demonstrates how static electricity is created and how current electricity flows through complete circuits, using examples like a train and various experiments. The film also discusses the ...

In high-power systems, current flow must be stopped, rather than limited, to protect circuitry effectively. Mechanical circuit breakers offer low losses and perfect isolation, but they can be slow ...
