thanks audioguru
i noticed that regardless of the value of the collector resistor that limits IC, IC can still increase if IB increases.
For example I calculated Ic to be 80mA with a resistor of 63ohms. This does not mean that the maximum Ic that can ever occur regardless of how high I drive Ib will still remain strictly max at 80mA but will still have the capability to go up if Ib goes up..This is an aspect of transistor-ing that always leaves me baffled. Could u help me iron out my thoughts on this?
