I am new to the world of computer science. I learned C language last year in my university. I also have a basic knowledge of OOP concepts and C# I want to learn Computer Graphics. I found this book named "Computer Graphics Using OpenGL by F.S. Hill" in the Library. The copyright year of the...

If a loop is moved in a uniform magnetic field such that the direction of its motion is perpendicular to the magnetic field, then no change of flux occurs. Then according to faraday, no emf is induced... But I was thinking that can the emf be produced in it due to the deflection force?

@technician ... thank you for your time.. reading your reply, a question came in my mind... resistances absorb energy... If no current flows through a resistor, that means no energy absorbed and as you said, no power dissipated... I have learned that electrons lose their potential energy as...

the equation P = (E2R) / [(R-r)2 + 4Rr] We say that when R=r , P = E2/4R which is said to be maximum.. But if I say R→∞ , then r→0 and then P = E2/R which is greater.. So, shouldn't power be maximum for max R ?

why does the hydration energy decrease as the size of the ion increases? I want a logical reason... I already know that it is because the charge to size ratio decreases...

This is NOT a homework question.. It is just something that is bothering me... 1. If two neutral conductors are made to touch each other, no current will flow.. 2. If a neutral conductor is made to touch with a positive conductor, the current will flow from the neutral to the positive...

Hello, I was confused about which bond is stronger, ionic or covalent... thinking and searching about that, I found (or better, realized) that when we talk about the boiling point of water, its just that it's INTERMOLECULAR forces get weaker, not the covalent bond present between the ATOMS ...

I was talking about the electron current... thanks for all the help... I was just revising some of my concepts... thanks

@studiot Thank you so much... it really helped, your second comment just one more thing to ask... figuratively speaking, if you move the accommodated electrons from the positive end through the battery and back from where the cycle started? is that what you meant??

@studiot.. thanks for the answer.. but i already know all of it... i am asking something else... HOW is charge carried by mobile electrons? Is it like when you apply potential difference, then the mobile electrons present in the material are attracted towards the positive plate and move...

When a point charge is put in a medium, it polarizes the medium and thus reduces the total electric field inside the medium... I don't understand why does the electric field reduce when the medium gets polarized... My question in other words is that, when we look at the coulomb's law, we see...

air, glass, mica, rubber, water, etc all are insulators because they don't have free charges to carry the current... I don't understand what do we mean by "carry"?? i mean, i don't really understand what happens at the micro level during electrical conduction through a medium...How do the...

@ tiny tim... ohh! thanks :smile:

What is a point charge? I have read wikipedia but m not much satisfied... please can you explain me in your own words? thanks
