Transistor symbol | Class 12 (India) | Physics | Khan Academy

Let's explore the symbol of a transistor. We will also see the motivation behind this symbol.
Class 12 Semiconductors: We cannot imagine our life without computers today. But what makes a computer tick? What's making this technology grow at such an exponential rate? It's all due to semiconductors. As unbelievable as that might sound, altering the properties of semiconductors allows us to build these computers. In this topic, we will explore the world of semiconductors. It's a journey from what semiconductors are all the way to creating building blocks of these computers.

[narayanastudent]

the way u draw those lines and arrows is so satisfying

[sanidhya]

A very good explanation about the topic

[Spear]

if you feel u unappreciated i am here and I'm really grateful

[lovi-editz]

Thanks alot, now i understand how to identity npn and pnp type

[PavithranD]

Great visuals and explanation sir but i have a doubt ...if we attach a positive voltage to the base of PNP transitor, wouldn't that become reverse biased??

[jechezhiyan]

How can the base terminal of a transistor be both positive and negative at the same time in a common base configuration?

[ruzainiahmedh]

Can someone explain what will happen if colector base junction also forward biased?

Why emitters small in comparison to collector
