Thanks , i needed a description I have access and i will use it

so how can i apply the dv=-E.dr in circuit to measure a potential across a resistor or capacitor to get to the v=IR ...also what is the lorents force...i got from u that if i have a stright line cylinderical wire and a battery then i can i measure by dv=-E.dr but for easiness i get it by v=IR

I am about to enter the department of electrical engineering in my engineering faculty as i am in my primary first year in the college and my question what will i study ?

Please anyone explain that to me as i cannot get it .How to link the potential difference which comes by integration dv=-E.dr like the potential inside and outside a charged sphere and the potential which comes by V=IR in our daily circuits how that comes i know that these are basics but i still...

what is that equation and what is t' ? and also if i say that velocity depend on time i can write an equation of time and velocity but i can't say that time depends on velocity .I meant something that time depends on.( in your example i can say that h is directly proportional to t but i can't...

It is the question ,I had posted some threads but i couldn't clarify my idea but now i came with the question . Can time be T=f(p) ?

Thanks for contribution and help, but I have another question , What can I do to study intensively if I wanted to enter an exam after a month and I wanted to study a book of about 500 pages and I want to get the highest possible marks?

What is the best studying method?? What is the best method for getting knowledge and information and studying in less time?also What is fast reading and is it only convenient ?How can I depend on self study i.e only books and online resources?..Thanks

ok all in all can I deduce that at certain conditions it can be that farther objects and near ones appear the same size...

My idea appeared as i got in another post that it is something like parallax but at some specified conditions ...it may be unuseful

I think that there must be a scientist that explained this phenomena...so who is he to see what he had done?

I was violated for telling that infinity is a number .but i think i said that you put a number refers to infinity in a formula. cm and m and i put 10^1000 km what will happen,that's all..try it in any formula will find results that don't refer to our observed reality so i think it is one of two...

How was the speed of light proved to be 3*10^8...also How it was proved that nothing can exceed the speed of light?...and what will happen if something moves under the effect of certain force with constant acceleration in space i.e the net force on it is constant and not equal zero...is that...

Yes I read and understood,my question is can we make something that recognizes every thing at certain image size irrespectable to how far are objects..? thanks...

sorry,but infinity is a number if i tell you an equation that deals with number from [-10,10] and i put 10^(10^10) or 10^-(10^10) by that method you can make one of two 1-find that the rule is broken or 2-explain that in nature the force affecting a wire in magnetic field=BIL and magnetic field...
