Physics

current that flows into opposite direction alternately. constantly being reversed back and forth. can be converted from high voltages easily using transformers

a device that increase or decrease the alternating voltage in electrical power applications. transfers electrical energy between 2 or more circuits thru electromagnetic induction

home and office outlets, capable of power electric motors, useful for many large appliances (refrigerators, dishwashers, etc)

current that flows in one direction only. no change of magnitude of the current, also called steady direct current.

flashlights, cellphones, laptops, batteries, usb port, ac adapter

states that the induced voltage in a circuit is proportional to the rate of change over time of the magnetic flux through that circuit

manifests the electricity and magnetic forces

You can create a higher value of emf if you have a higher change in magnetic flux.

is a material in which electric current does not flow freely. atoms are tightly bound electrons which cannot readily move.

device that stores electrical energy in an electric field. a passive electronic component with two terminals.
