Introduction to Transformer Theory and Ratios Transformer theory describes how a transformer steps voltage up or down in AC (alternating current) circuits.   On a transformer, we have primary windings, and secondary windings.   The primary winding induces a voltage into the secondary windings that is proportional to the number of Read More »

Introduction to Calculating Power (Watts) If you are not familiar with calculating resistance or current, please visit these posts.   This will help you better understand basic electrical principals before trying to calculate power. The Unit of power is the WATT.    Power itself is easy to calculate, but we Read More »
