Discuss analogies and differences between Gauss’s law and ampere’s law.

Analogies between Gauss’s law and Ampere’s law: Gauss’s law says the electric flux through a closed surface is proportional to the charge within the surface.Ampere’s law says the line integral of B.ds around a close path is proportional to the current that passes through that path. In Gauss’s law,the imaginary and arbitrary closed surface is taken enclosing a charge.In ampere’s ...

Discuss analogies and the differences between Coulomb’s law and the Biot- Savart’s law?

Similarities: Both the electric and magnetic field depends inversely on square of distance between the source and field point. Both electric field and magnetic field are proportional to the source strength namely charge and current element respectively. Both obey superposition principle. Differences: According to Coulomb’s law,the electrostatic force between two point charges is directly proportional to the product of their ...

What is plasma physics

“The branch of physics which deals with the study of the properties of plasma is known as plasma physics.” Plasma definition: A highly ionised gas is regarded as a fourth state of matter called the plasma state.It is regarded as fourth state of matter since it is not solid,liquid or gas in usual sense. How to create plasma? The kinetic ...

Why resistivity of semiconductors decreases with temperature?

The solid materials having properties in between conductors and insulators are known as semiconductors. A semiconductor is a material which is neither a good conductor nor good insulator of electricity.Its resistivity lies in between conductors and insulators,which is 100 Ω cm.The energy gap between conduction and valence band is narrow for semiconductors with respect to insulators. With the rise in temperature ...

Why does n-type semiconductors have so many electrons than holes?

The elements of group V are pentavalent such as arsenic (As) ,phosphorus (P),bismuth (Bi),and antimony (Sb).These have five electrons in their valence band.When one of these materials is added to semiconductor like Si,four of its valence electrons from four covalent bonds with neighboring Si atoms and the fifth electron becomes free.The numbers of free electrons is equal to the numbers ...

In our body,are there more neutrons than protons?

Human body mainly contains water nearly 70 %.In all neutral atoms,the number of protons and electrons are equal.If you did have many more protons or electrons,yous body would become electrically charged,but normally ,the amount of protons and electrons are the same. Of course the human body contains many different elements,and some of these are of high atomic number.On the other ...

What is difference between Electrostatic force and nuclear force

Electrostatic force: Electrostatic force acts between charged particles only. Electrostatic force is a long range force. A proton can interact with all the protons within the nucleus through electrostatic force. Electrostatic force is a weak force. Nuclear force: Nuclear force acts between the nucleons and it is independent of the charge. Nuclear force is short range force. A nuleon can ...

Why are some lines in the hydrogen spectrum brighter than others?

In hydrogen spectrum,some spectral lines are brighter than others depending upon their energy level.These bright lines show that electrons have jumped from higher energy level to lower energy level.When electron jumps from some higher orbit,the energy released in the from of photon will be greater,and we get a brighter line.Thus in hydrogen spectrum some lines are brighter than others.

Is an electron a particle or a wave?

In 1924,de Broglie proposed that particle acts as a wave and wave acts as a particle. Davisson and Germer experimentally confirmed the wave nature of electron.They showed that electrons are diffracted from metallic crystal in the same manner as x-rays and other wave.Hence electrons show wave like properties.J.J Thomson while measuring e/m of electron showed that electron is a particle.Thus ...

Why is wave nature of matter not more apparent in our daily observations?

Since,the de-Broglie wavelength is given by the relation λ = h/mv As the value of Plank’s constant is very small,so the wavelength associated with ordinary object is so small and is difficult to observe.In our daily observations we deal with the objects having larger mass and smaller velocity,that is why the wave nature of such objects is not more apparent ...
