Power & Motion
How Does a Transformer Work?
Two windings and a changing magnetic field raise or lower AC voltage.

Power & Motion
Understand how energy becomes charge, heat, motion, and useful work.
Power & Motion
How Does a Circuit Breaker Work?
Current-sensitive triggers release a fast contact mechanism before wiring overheats dangerously.
Power & Motion
How Does an Electric Generator Work?
Mechanical rotation changes magnetic flux and transfers energy into an electrical circuit.
Power & Motion
How Does Regenerative Braking Work?
The wheels drive the motor backward as a generator, recovering energy while slowing.
Power & Motion
How Does a Heat Pump Work?
A reversible refrigerant cycle collects heat in one place and releases it in another.
Power & Motion
How Do Wind Turbines Work?
Aerodynamic lift becomes rotor torque, then a generator turns motion into electricity.
Power & Motion
How Do Solar Panels Work?
Semiconductor junctions separate light-created charges and contacts collect the current.
Power & Motion
How Do LED Lights Work?
A controlled semiconductor junction releases photons while optics and cooling make them useful.
Power & Motion
How Does an Electric Motor Work?
Electrical current creates a magnetic chase that turns a shaft.
Power & Motion
How Do Batteries Work?
Electrons take the useful outside path while ions balance the reaction inside.
