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.

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?

hi what if the value on the emitter and collector are the same, is the transistor bad? than you.

My collectors and emitters are the same. So how can i know then who is who?

Welcome

[@user-fm1cz4qd6m]

How can find the base? MOSFETs we find with the same procedure? Thanks

[@TechStudyCell]

Identify BASE terminal: You will not get any reading in multimeter across the collector & emitter terminals. But if you connect the Red lead with BASE and black lead with collector or emitter of NPN transistor you will get reading. For PNP transistor you will get reading by connecting the Black lead with BASE and Red lead with collector or emitter. Please refer the following videos for MOSFET: kzbin.info/www/bejne/f3eaZWN7asegbpY

[@andresbatacan463]

In PNP connecting collectors and base no Number coming out and connecting base and emitter there is a Number . Question what is the status of the transistor?

[@alphajuliet5697]

Wow! Awesome 👌 video 📹

[@thebrokeway9838]

thanks I really needed to learn this

[@TechStudyCell]

Great!

[@vivekkumar-tk8lj]

If reading shows voltage drop then what will be its unit. Kindly explain, I will be grateful to you.

[@TechStudyCell]

thanks

[@jacobafurr4877]

Awesome. One thing though. Current doesnt always flow from anode to cathode. It depends on the charge. Only - charge will flow from cathode to anode but + charge will flow from anode to cathode.

[@dougiefresh730]

So on a PNP transistor if I get NO reading between middle(black) and either outer legs(red) the transistor is bad?

[@TechStudyCell]

Yes

[@dougiefresh730]

Ok. So what if I get nothing from the middle to either side but I get a reading from the left to the right, what does that mean. Thank you.
