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.

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

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
