6. Basic Electronic Theory > Basic Concepts in Electricity

Basic Concepts in Electricity

Let’s learn a bit about some basic electricity concepts such as voltage and current. Electricity is the physical phenomenon of moving electric charges (electrons), but for most of the things we’ll do, it’s simply the flow of electrons through metal wires and circuit components. The three most important properties of the flow of electricity in a circuit are the voltage, the current, and resistance.

Voltage, Current & Resistance

Voltage

Sometimes called “electric potential,” this is a measurement of how much the electrons want to move from one location to another. The way it works is that the higher the voltage, the stronger the “pressure” for the electrons to move from one location to the other. Voltage is measured between two points, such as between the + and - terminals of a battery, or between two points in a circuit. Voltage is measured with “Volts” and is abbreviated with the letter “V.”
