Because we frequently deal with phasor voltages and phasor currents in HSC...... Its assumed constant frequency. If it weren't constant frequency at a rate which is used everyday (say 50 Hz) then yes the torque applied would not be sufficient to keep it rotating at the same speed. Is this you...

96 Similar situation to me but I did 4U. Though I did terrible in English.

If only you could all see what happens in other subs. Its like we can get 100% in quizzes but the actual exams are like wat.

The thread is over two years old and the books are different now.

^^^ I've been using that for everything except maths which is separate.

AC generator generates an alternating current (which flows in both directions) when it undergoes generation. The direction changes every half turn. In a universal motor, the polarities of the field winding and armature winding both reverse as they are in series with each other, which causes...

Just walk out of the room and go to the toilet. You might of well just screamed out in the lecture room that you needed to go to the toilet if you are asking the lecturer. Dream-Big strikes again.

In response to the message. It should be covered in year 11, but unfortunately school physics tends to disregard the fundamentals of circuits. Honestly all you are doing is learning how KVL and KCL work, but they never formally introduce you to it, even though it should be introduced.

cringing.... I looked at it briefly and I already have a Monday night lecture clash I think (I looked at it for 2 mins though so I could be wrong).

I had a tutorial get moved rooms one week before O-week, after I had already printed out my timetable, without notice. Its possible but highly unlikely.

You won't even start that stuff until second year. Maybe in second semester first year if you are privileged enough. So you have plenty of time to read up on it. Also, for something like that they start from scratch. Probably the only thing you need at the moment is a good maths and mechanics...

This is why we should have been introduced to Kirchoff's voltage/current laws in year 11. If you feel at all confused about it, then I suggest you look up KVL or KCL. You can ask me if necessary too. However, be aware that although KVL and KCL make up the basics and are easy to understand...

Sensible choice. I think it will be worth it in the end to just do what the teacher does in your situation. Anyway there is a much higher chance you will use the stuff you learn in Medical for everyday life or random stuff later on.

Honestly, my multi is still better. Because you can use them for buses even here in woop-woop (my area). Can't use Opal except for train rides here though. The other good thing about using the tickets is that you can just buy the travel tens and load them in your arsenal for whenever you need...

Oh right I get it now. Higher priority basis type stuff I guess. It would be more convenient if higher year students had higher priority so that they can get their degree done on time.

I have a friend that drinks a lot of alcohol. Does 17 L for every 100km. Maybe I should start filling him up with unleaded 95 instead of alcohol :p

Meanwhile I have to deal with mine a week after you D94. Would have been much easier if it were to be done next week. Oh well may as well get it ready next week and fill it in 2 seconds on the day I can do it.

This thread is two years old and OP already finished HSC lol.
