Hi everyone! I'm Rhys, pleased to meet you all!
Hoping to get some really quick help with a voltage regulator problem.
I need help calculating the power dissipated in a bipolar transistor that is set up as a voltage regulator.
I've been trying to find info for two days now- my textbook, which has been really good up till now, is useless.
Here is the circuit:
Vin= 25V
Vz=15V
Hoping you can help me- I am not sure how to go about calculating the values I need such as Ib and Ic and really just not too sure in general how to go about this- please help!
I am not too sure what formual to use; I have unfortunately seen a few I think the correct one is P=Ic(Vce+(Vbe/Beta))?
Is Ve= Vo?
Therefore is Io=Ie = 14.3V/10k?
I am not sure whether Ie is still roughly = Ic or not?
I am not sure how to find Ib, is it = to Vin/R1?
Any help would be appreciated!
Thanks,
Rhys.
