Testing full wave rectifier with 20 to 40 voltage source.
In this activity, we designed a full wave rectifier sourced with 20-40 voltages. A full wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into pulsating DC .
Installing of two 3-way and two 4-way switches controlling lamp from 4 location
A light or lights can be controlled by more than one switch. The usual practice in home construction is to use 3-way switches. "3-way" is the electrician's designation for a single pole double throw (SPDT) switch. In this video, we Installed two 3-way and two 4-way switches controlling lamp from 4 location. We passed the activity/practical through hard work and team work.
