TRANSFORMERS – What They Are, How They Work, How To Size Them

Let’s open up a transformer and dig through it to see how they work. Transformers are extremely useful devices used in electrical systems to raise and lower voltage. They’re also used for isolation, typically in cleaning up power. They only exist in the world of Alternating Current however, so in DC circuits you won’t find transformers used. Read More

Episode 18 – Resistance (Ohms)

Resistance is one of the most crucial aspects of an electrical circuit.  Along with Voltage and Amperes, Resistance plays a major role in how a circuit operates. Read More

Episode 16 – THEORY – Electric Current (Amperes/Amps)

Electric current is one of the hardest things to wrap your head around when you're first getting into the electrical trade.  Many apprentice electricians get confused with the difference between current and amps.  Well, that's because people talk about electrons and charges and interchange the terms without really knowing what the difference is.
