Two short circuit protection circuits are compared. one of them provides isolation and the other one has faster response

Hello my Friends,

This is my first post in this website. I will be posting regularly !! so I hope you stay tuned :)

My style of posts will be concentrated on videos so you don't waste your time reading long articles

In this article I want to share with you a video that I created, where two short circuit protection circuits are tested, compared and explained theoretically and practically in details.

Click me to watch the video :)

-Relay based circuit components:

Relay - 2 LEDs


2 diodes

1 push button.

-Transistor based circuit components:

PNP Transistor

NPN - Transistor

2 LEDs

4x 1kOhm resistors

1x 10kOhm resistor.

Let me know your feedback and see you in my future posts ;)
