Hello, I have a quick question about Characteristic curves. [PLAIN]http://pokit.org/get/1958a855486487230cd4e3c0a1cc0908.jpg [Broken] First: Do these curves go to infinity, i mean in theory? If I had a steeper load line, I would hit saturation later. And what about that portion of load line between Ic axis and that curve? It doesn't intersect anything. Is this saturation? Or is saturation only that point on Ic axis that is mainly limited by the collector resistor? Saturation is really giving me a headache, even after countless PF posts about it. And should I look at this load line in couple with output characteristic? It confuses me that at 0 V you have Ic max but there are no lines from output characteristic to intersect.
