Hello members, can u pls solve my confusion immediately//
what is resistance/// In textbuk, it says the resistance is caused when the free-mobile delocalized electrons, which are mobiling to and fro, collide with the electrons that are orbiting around its orbitals of the metal lattice atoms, causes the resistance.
THAT MEANS WHEN they both collide, there is a repulsive forces between them due to like charges, so this causes them to repel each other and move apart with small/large distance. That depends on the way they collide and the amount of repulsive force they contain. The distance that they move apart is considered as a space, where the charged particles, which is the current, can flow easily without any difficulty. But this happens only when the temperature has increased not decreased / at room temperature.
Because when they collide, they both produce/feel repulsive forces, this repulsive forces is dependant. Because with higher temperature, more free-delocalized electrons and the electrons that are orbiting around the atoms, gain more kinetic energy and are excited state and unstable state and therefore they move at higher speed randomly and they both will collide with each other frequently with short period of time during collision, but they will feel very less repulsive forces, because both carry high amount of kinetic energy. So this gives more space for the flow of charged particles to move easily, hence this decreases the resistance.
Is my explanation correct?? May I know resistance is present in every electrical component? Is there any other electrical component, which does not have resistance?? if there is no, can u tel me why there is no resistance in any electrical component only few?? Can I relate the concept of friction to this concept?? when they collide, they cause resistance. But how??
may I know how charged particles produce magnetic field, when charged particles are moving through the conducting wire??
Normally a point charge either could be a positively charge or a negatively charge, they both will create their electric field// am I right??
so when a point charge creates an electric field, this point charge starts to accelerate and according to newton second law, this point charge produces the force. But i dont know how the charged particles produces the magnetic field and why do they form in a circular form, which is a magnetic field, around the conducting wire?
May I know when a point charge creates an electric field, which is a region of space, how can the point charge starts to accelerate through the field??? when a point charge creates the electric field and if we place another point charge on this field, then that charge can accelerate but NOT the point charge, the one who creates the electric field. AM i correct? So again here confusion, how a point charge is accelerating when this point charges creates an electric field??/
Sir what is electromotive force? It is the force, that pushes the electrons which carry negative charges inside the battery/power supply to move through the circuit. AM i correct??
Sir why in textbuks says, that the current flows from positive terminals to the negative terminal, which is called the conventional current?? Just image the proton carries positive charge and it is inside the nucleus of the atom. So how can the protons move through the circuit, when the electrons, which are too small in size, can move freely???
Sir when I asked myself what is the current, the textbuk says it is the flow of charged particles, that means the flow of electrons or the flow of protons??? If u say flow of electrons, why the protons cannot move, even though they carry charge// Maybe u would say that they are located in the nucleus , which seems to be far away when compare to the location of electron. Am I correct??
Sir electron and proton, they both carry charge// Right. So what does the charge contains?? I mean i know that proton carries positive charge and electron carries negative charge, but I want to know what does these charge contain? if there is no such description for that, its alright.
Need ur reply urgently//
If u dont know, pls can any one of the member inform this confusion to Sir astarmathandphysics immediately. Pls help me .. plssssssssssssssssssssssss
