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 39 – Using Ohm’s Law In The Field – ELECTRICIAN MATH REAL WORLD EXAMPLES

Doing math, for many people, is one of the things that holds them back from advancing in their career as an electrician.  “I’m just not good at math,” I often hear.  Knowing how to apply Ohm’s Law calculations in the field is crucial for your ability to think critically, on the fly, about what may be happening in a circuit - and electrician math is really not that scary.  Let’s dive in.

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 14 – Difference Of Potential (Voltage)

In order for electricity to work, there has to be movement. Static electricity still needs movement to occur in order to discharge and equalize charges. The only way that movement becomes useful is once there is a difference of potential present. That is what voltage is all about. Read More
