How to test Transistor with Digital Multimeter -Identify base emitter collector & PNP NPN transistor

In this video I have shown how to test BJT transistor using a digital multimeter. In this video, I have discussed the forward bias and reverse bias, how to identify PNP transistor or NPN transistor and how to identify base emitter and collector of a transistor.
Here I have used BC557 and BC547 for testing the transistor terminals.
I recomend you to watch complete tutorial video of the transistor testing but you can click on the following timestamps to skip any portion:
00:42 Forward Bias and Reverse Bias connection
02:35 How to identify PNP or NPN transistor
04:39 How to identify base emitter and collector terminals of a transistor
After watching this video you can easily identify PNP or NPN transistor legs without any transistor datasheet. In this video I have shown steps for testing a BJT transistor with a multimeter so that you face no problem while testing any transistor.

You all prolly dont give a damn but does anyone know a method to get back into an instagram account..? I somehow forgot the login password. I would love any help you can give me!

[@johanjoseph2190]

@King Logan Instablaster =)

[@kinglogan4029]

@Johan Joseph I really appreciate your reply. I got to the site through google and im trying it out now. Looks like it's gonna take quite some time so I will reply here later with my results.

[@kinglogan4029]

@Johan Joseph It worked and I actually got access to my account again. Im so happy! Thank you so much, you really help me out :D

[@johanjoseph2190]

@King Logan No problem =)

[@smellymomo]

I love how you explained the workings of the transistors as well. Helped me understand more. Thanks

[@talilkr5238]

After watching several videos on how to do it, was about to give up. This video finally made me understand, the best and the simplest video. Thank you so much.

[@minilab9030]

This is excellent. Tempting to copy your diagram and put it up for easy reference near my bench. Exceptional clarity...great teacher.

[@TechStudyCell]

Thanks for the feedback

[@WistrelChianti]

Thanks! This has made sense for the circuit I was trying to reverse engineer/figure out.

I have a A928 H 05Y at my hand at it's a pnp transistor. But voltage for bothe pn junction is exactly the same at 703. Now I know the base but how do I know which one is the collector and emmitor?

[@mohammedyasin4138]

Superb explanation I love it 🥰💕💕💕

[@AloisPalen-yh6bn]

Good explanation, thanks.

[@vivekkumar-tk8lj]

By using multimeter in diode mode and checking diode or transistor we get reading like 784 or 658. What this reading shows?
