My book (The Art of Electronics by Paul Horowitz and Winfield Hill) is stating something that seems to be the opposite of the example it is using. I am not going to school for my studies so I apologize for having no go-to resources but here. Can anyone shed light on where I'm getting confused?
I'll type out the relevant bits: "A transistor is a 3-terminal device available in 2 flavors (npn and pnp), with the properties that meet the following rules for npn transistors: 1. The collector must be more positive than the emitter. 2. .... 3. .... 4. When rules 1-3 are obeyed, IsubC is roughly proportional to IsubB and can be written as IsubC = (hFE)(IsubB) where hFE, the current gain (also called beta), is typically about 100. ... When the switch is closed, the base rises to 0.6 volt (base-emitter diode is in forward conduction). The drop across the base resistor is 9.4 volts, so the base current is 9.4mA. Blind application of rule 4 gives IsubC - 940mA (for a typical beta of 100). This is wrong. Why? Because rule 4 holds only if rule 1 is obeyed; at a collector current of 100mA the lamp has 10 volts across it. To get a higher current you would have to pull the collector below ground."
My question is isn't the collector more positive than the emitter in this case? The collector has 10 volts and 100mA. The emitter is literally connected to ground. The collector is therefore more positive than the emitter. Is it not?
