I know the formula of collector current is:
But my RL is a potentiometer, if I adjust it to 0Ω, how do I calculate the current?

It's definitely not infinite. Let me give you a hint and think about it at another level.

VB=VBE+VE=VBE+IE*RE, and because IC≈IB, it can be transformed into (VB-VBE)/RE=IC

So what you need to know is that the collector current is independent of the collector load.

The simple constant current circuit Ur2-0.7 divided by RE.
