Hi:
Please look at the image below. I'm having trouble understanding how these formulae come about. This diagram is showing conventional current, I believe. And it is an npn BJT biasing.
The first part says the voltage across a forward biased junction is 0.7. I think this is because it acts like an np diode.
But it says:
How can this be if the current is flowing from the positive terminal (conventional current)
And what is the reason we have two voltage values?
Any help please
