Yes

Yes
Ok thanks. Also if you got an answer like 21.224567 how many decimal places would it be rounded to?

A sig fig range between 1-4 is acceptable, However I'd round to the amount that's in the question if you know what I mean.

Yeah ok thanks
5. Okay guys my teacher said that this example will most likely come up in the exam and you need to remember to do 5.0 - 1.6 = 3.4 and use that in the V=IR equation when the circuit is has an LED...

Do not use 1.6 alone

6. Also I confirmed that total internal reflection and critical angles arent in the exam Ethan100
7. Also my teacher said to know how to label transistors and mosfets and know what voltage they may operate at and how its different from a switch
8. Transistors dont break a circuit when not active do they?

What is the operating voltage for a mosfet?

Exactly what you need to know that they dont and a switch can, transistors are always "like closed switches but they operate electrically rather than manually. A switch you have to open and close yourself" - what my teacher said

It operates at 2.0V or above

It operates at 2.0V or above
Thanks

18. Oh yh it's an afternoon exam, forgot that.

Do not do wa=hat I did and misread the question. As a result of this, I am currently planning on the best method to commit
19. OMG!!

Amazing paper!!!
Apart from that silly metal stick question, didnt know what to answer for that??? Lmao
20. My invigilator wouldnt let me take the multiple choice!!!

i have to trek to my science campus now to ask for it.
Invigilator can suck my ****

I always get the same invigilator and never lets me take the mc lol...
