Hello everyone
The most difficult area in electronics for me so far into my first semesters of college has been working with transistors. I don't know if it's because I'm just thick, or if the instructor just can't explain this stuff in a way that I understand. Maybe he uses terms that I can't research and make sense of. Either way, here is a situation that comes up regularly that stumps me every single time.
Q. A transistor has a Beta DC of 75, VCC = 15 Volts, RC = 1000 ohms, VCE is 7.5 Volts VBB is 5 Volts. What is IB and RB?
For the life of me, I don't have the slightest clue how to calculate IB and RB without at least already knowing one or the other. Nor can I get IC without IB, so I can't invert that equation to get IB because I know of no other way to calculate IC.
If I felt it necessary I'd take a picture of my desk right now... it is littered with scrap calculations that arrive nowhere. If anyone could help me with this I would greatly appreciate it.
