Step down transformers explained, fusing, voltages, resistance check | methods & tips |

A video demonstration of the basic step down power transformer. This will including fusing, proper connection of the fuse holder, measuring secondary voltages with the digital multimeter (DMM) and how to test the transformer with the ohm meter. For this demonstration a center tapped secondary winding transformer was used. The demonstration is set for a beginner with entry level electronic or electrical experience. Please watch the additional videos using the DMM, other test equipment, and on soldering techniques.
