Watch Alain de Bottons status anxiety(the 2 hour or so video, not TEDtalk) if you are getting depressed or angry about it...I hope it can help bring some new perspective. Cannot link it here.
No we have actually never used lightbulbs, we are now dealing with more complicated things. :p
Anyway the prof always laughs at my circuits and my feeble understanding of this field.
Yes, I also know this, and in AC signals electrons dance back and forth, but he was teaching something about a BJT in a switch mode when he mentioned it. He has worked a lot in industry and has some patents to his name too :eek: so we all take him very seriously
yes he is a prof, he is amazing and can look at circuits and knows all the available resistors of a certain series and other electronic components by heart. He can see your circuit from miles away and come and correct it. :-) He can caclulate resistances in his head and just by hearing any...
An ideal voltmeter is one that has infinite resistance. Use KVL, the resistor to the rightmost (nearest to terminal A) is short circuited anyway, so you are left with two resistors of equal resistance.
All measuring devices conncected to a circuit adveresly effect it, ideal ones dont. Since a...
my professer said the circuit is "accelerated" when the total resistance seen is decreased or current somehow increases, it makes sense as current is the organised flow of charged particles in a given time period and resistance can be thought as analogous to friction or opposition to motion of...
In a parallel circuit, the total equivalent resistance "seen" by the circuit decreases as more resistors are added, irrespective of their value. The parallel resistance is always less than or at most equal to the value of the smallest resistor in the circuit.
The greatest current flows (V/R)...
Degrees are becoming more watered down and less theoretical by the day, as seen by many universities in the UK who can accept people with bare minimum of A levels. The good universities will know better and maintain their standards, with so many people opting for a degree for whatever reason...
this is normal as your teachers are probably not very good, i wouldn't worry about it as maths is a very strange subject indeed, just learn as well as you can and get some philosophical outlook on it (you may search for books or internet). Usually pure math courses in school tend to be the...
You are doing extremely well in calculus so no doubt you can do well in a physics program, because mostly competence in maths is most important when starting a pure physics major.
My only advice to you is to learn as much mathematics as you can, starting with a good grasp on basics like calculus, analysis, trigonometry, some linear algebra and *maybe* set theory, logic and proofs. Because this will help or make it easier to understand the physics later on!
it was vague but this was my intention at the time:
I am sure it is not worth investigating any longer, and probably founded on wrong ideas/lack of knowledge. Thanks for your time.
Few people in business or government care for ethics. :/
you must patent your ideas/technology, and even then it will surely be reversed by someone (but not sold in the market covered by the parent I guess). I read somewhere some defence products that are sold have restrictions on the buyer...
Thank you. I think, part of the problem for me is that I have no idea about what to do for my father . I should've never left his side, but I didn't get into the universities here. He said he will not accept me leaving university.
I made a load of mistakes along he way and didn't know any...
