How Does It Work? DC Current & Voltage Source


This video, part of the Lake Shore Academy video education series, demonstrates the theoretical operation of a DC current and voltage source as well as some notable implications during practical application.

This series of animations shows a simple experiment with a DC source and device being tested, where voltage is represented by the height of the circuit and current is represented by the speed of the particles travelling within the circuit. This visual representation of Ohm’s Law (V=IR) in three dimensions attempts to make the concept of electrical phenomena more easily understood. Voltage, as potential, is depicted as height. The resulting voltage drop from a resistor is depicted as a figurative drop from this height. All visual depictions of electricity will fail to describe what is occurring with complete accuracy, though hopefully this method succeeds in explaining the concepts where some have failed.
