Follow the current Remember that we call a collection of connected electrical or electronic components a “circuit” because currents always flow from a source to a load and then back via a return ...

This pressure difference causes water to flow around the loop – just like the potential difference produced by a cell or battery causes electrical current to flow in a circuit.

Many introductory books on electricity try to relate voltage to water pressure, electric current to water flow, and resistance to changes in pipe volume.

As the current flows through the PTC thermistor, it will quickly heat up and its resistance will quickly increase to a point where the current flow will dramatically reduce, essentially removing the ...

Circuit breakers are a safety feature that automatically interrupts the flow of electricity in the face of a system fault or ...
