The diagram showing the current directons for npn and pnp not correct in the link above.

Thanks.

 

Actually it is right, since it is showing electron flow. However, I do believe it could be made more clear.

 

I have to agree about it being correct, since electrons flow from negitive to positive.

That is pretty much covered here...

Yes it is right I missed the electron flow bit.

thanks.
