Ohm's Law is simply a math triangle electricians use to calculate Voltage, Amps, and Resistance in a SUPER EASY way. It's all based on RESISTANCE being constant.

In electrical circuits we have a power source and electrical loads. A power source is what provides power to the circuit, whether it's an AC or DC circuit, and an electrical load CONSUMES power from that power source.

A brief overview of Voltage, Ampacity, Resistance, and Power for those apprentice electricians going to school.

A basic electrical circuit works by connecting two wires (Hot and Neutral) across an electrical device (known as a "load").

How circuit numbers work in a three-phase and single-phase panel, and how to share a neutral with different phases safely.

A name plate identifies how to satisfy the electrical demand of equipment. It often clarifies VOLTAGE, AMPS, PHASE, Model and Serial Number, and Hertz (Frequency) of the electrical equipment.

Electricians use higher voltages to reduce current, which in turn allows for smaller wires. This saves money, and is much easier to install and maintain!
