R6 will come into play at some point as it is the only component that can deliver base current when the input voltage is at a positive peak and the limited base current it delivers x beta may cause additional volt drop across the upper transistor making VCE (saturation) more like 1 volt. | |

| May 11, 2020 at 17:10 | comment | added | TechnoKnight | this is an exam for electronic/electricity. I can't depend on a judgement or something inaccurate like that to decide what voltage matters and what voltage doesn't matter. I either don't include it every time or I include it every time. | |

| May 11, 2020 at 17:02 | comment | added | TechnoKnight | wait, what? I can't depend on something so inaccurate in an important exam, you know. | |
| May 11, 2020 at 16:59 | comment | added | Andy aka | @TechnoKnight no, you use judgement. BJT and MOSFET circuits require judgement on what is important to include and what is unimportant so that it can be ignored. If you want to include stuff that another person might think as trivial then there's nothing wrong with that of course. | |
| May 11, 2020 at 16:58 | comment | added | TechnoKnight | Are we supposed to neglect VCE in every equation or calculation no mater the circuit or the voltage though? | |
