Hey, i was set this assignment recently and im stumped as to how to work it. Ive looked through notes but each transistor circuit differs so much that i can figure out the formulas to work out each part. Power rail +10v and 0v. NPN transistor is the circle (im not much of an artist) and the 3 points cbe are collector, base and emitter. Now questions are i have to find the emitter voltage, current, the (approx) collector current and the base current. The gain is also 100. Now i recall something to do with either Ib = Ic or one of them is so small its negligable. i just cant remember though. I do remember hfe = Ib/Ic, so finding the base current once others are answered should be fairly simple. Hopefully some one could explain the ideas behind this. If its not too much trouble, could some one also explain whats different when the resistor is switched to the collector line?
