The way in which voltage (V), current (I), and resistance (R) interact in any DC circuit was first explained by German physicist Georg Ohm. In the field of electricity, German physicist Georg Ohm discovered a key principle, he found that at a consistent temperature, the flow of electric current through a fixed, unchanging resistance is […]

Understanding How Electricity Flows in DC Circuits
As we all know electrical circuits consist of interconnected electrical elements. Current is measured in amperes (A), represents the flow of electric charge around a closed loop. This flow is driven by a potential difference (electromotive force, EMF) measured in volts (V). We know that, all materials are composed of atoms, however these atoms also […]
