  • X rays uses,properties and applications

    What are X rays ? X-rays are the electromagnetic waves that are emitted by the atoms of those metals which have a large atomic number, a large number of protons in their nuclei so that the pull of the nuclei…

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

    The basic difference between Gauss’s law and ampere’s law is that Gauss’s law is used to calculate the electric field while Ampere’s law is used to calculate the magnetic field. Gauss’s law is used in Electrostatic while Ampere’s law is…

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

    The difference between Coulomb’s law and Biot Savart law is provided here. If you want to learn Brief differences between coulomb’s law and Biot Savart law then you are at the right place. Keep reading.. Similarities: Both the electric and…

  • do electron tend to go to regions of high potential or low potential?

    Electrons are negatively charged particles.When placed in an electric field ,negatively charged plate will repel them while positively charged plate will attract them.So,the electrons will move from negatively charged plate to positively charged plate.Since positively charged plate is at higher…

  • 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 a semiconductor like Si, four of…

  • What is the Difference Between emf and Potential Difference?

    The emf (electromotive force) is the potential difference between the terminals of a battery when no current is flowing through an external circuit when the circuit is open. The potential difference is the voltage across the terminals of the battery…

  • Difference between conduction, convection and radiation

    There are three modes of heat transfer, conduction convection, and radiation. In the process of conduction heat transfer from a hot body to the cold body due to free electrons.In convection heat transfer due to the actual movement of molecules, While…

  • What happens when two waves interfere?

    Interference is the process of superposition of two waves having the same wavelength, amplitude, and frequency. When the waves interfere, there is no loss of energy. During constructive interference, the two waves are added up to give a resultant wave…

  • Uses of damping devices in machinery

    The damping devices are often used on machinery to increase the damping and reduce the vibrational effects caused due to running of machinery.These vibrational effects disturb the whole assembly and the building in which the machinery is working.The vibrational frequency…
