Circuit Breaker
Not too long ago, when electrical wiring was first being built into houses,
many people fell victim to physics. The unfortunates would plug too many
appliances into their circuit. Each appliance drew a certain amount of
current. When current is resisted, it produces heat proportional to the
square of the current times the resistance (
).
Because houses lacked superconducting home wiring, this hidden coupling between
electronic gizmos made the wires in the walls get hot, sometimes hot enough
to catch fire. Whoosh. No more house.
The fledgling energy industry found a partial solution to the problem of resistive heating in the form ...
