Electrical Circuits – the basics
Having trouble understanding how circuits work? Try working through this analogy. Current, charges, energy, an ammeter, a battery and a lightbulb are all being represented in this analogy. What is representing each concept or circuit component?
You can use the simulation below to build and explore different circuits.
