Episode 19 – Electrical Power (Wattage and Volt-Amps)

Electrical power is often expressed in two units, Watts and VA.  Wattage and Volt-Amps rather, get misused because many people do not understand the differences in them and when they should be used.  In this episode I break down the differences in the two terms and how they relate to one-another 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.

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...

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.
