How to Connect Triacs in Parallel for High Current Loads: Circuit Diagram

Last Updated on July 11, 2026 by Swagatam Leave a Comment

Sometimes we make electronic circuit designs, and then we see that one single TRIAC cannot take all the big current of a very heavy load. This heavy load can be a huge heater, a big motor, or too many lights. In this condition, we get a simple idea. We think that we can connect two […]

Blood Electrification Circuit: Explanation And Working Principle

Last Updated on July 10, 2026 by Swagatam 9 Comments

Here we are talking about one circuit which many people know by the name Blood Electrification Unit, and this circuit became known because of Bob Beck many years back in the 1990s time, so now people also call it Beck Blood Electrifier. This unit is nothing complicated looking but the idea sounds heavy because it […]
