A Practical Introduction to Transistors | BJT Transistors as a Switch

[@In3xorable]

Appreciate the information. Alot of people don't have this good of an explanation for bjts.

[@Shooo117]

likes your video. nice presentation on the concept 😄

[@lodymanchempa11]

But what is the purpose of the the first resistor (R1) if you are using a bench power supply? for the rest great video

[@ukoebenezer8307]

In your last schematic example, I saw 4k7. What does it mean??

[@overkillprojects8091]

It mean 4700 ohms. It's typical to write, e.g., 4k7 instead of 4.7k for resistor values

you are measure voltage using multimeter not current
