Explain Bohr's Atomic Model: Bohr's Atomic Model - Neils Bohr, a Danish physicist, put forward his model of atom in 1913. He retained Rutherford's model of a very small positively charged nucleus at the centre.…
Motion in Combined Electric and Magnetic Fields: The Motion in Combined Electric and Magnetic Fields is given by the below two names, namely Parallel Electric and Magnetic Fields Perpendicular Electric and Magnetic Fields Parallel Electric…
Motion of an Electron in a Magnetic Field: Motion of an Electron in a Magnetic Field - Consider an electron to be placed in the region of magnetic field. If an electron is at rest,…
Force in a Magnetic Field: Force in a Magnetic Field - If a conductor of length l metres carrying current I amperes is placed in a magnetic field of intensity B (tesla), and if B…
Two Dimensional Motion in a Uniform Electric Field: Two Dimensional Motion in a Uniform Electric Field - Let us consider that an electron enters the region between two parallel plates of a parallel plate capacitor…
What is Current Density? By definition, the current density, denoted by the symbol J, is the current per unit area of the conducting medium i.e., where current I is the rate of flow of charge.…
What is Electron Volt? The joule (J) is the unit of energy in the SI system. In some engineering power problems this unit is very small, and a factor of 103 or 106 is introduced…
Motion of Charged Particle in Electric Field: Motion of Charged Particle in Electric Field - The electric field intensity which is equal to negative of the voltage gradient, is defined as the force (in newtons)…
Rutherford Nuclear Model of Atomic Structure: In order to explain many phenomena associated with conduction in gases, metals and semiconductors and the electron emission from a metal surface, it is necessary to assume that the…
Single Mesh and Multi Mesh Network: Electric network may provide a single closed path (known as a mesh or loop) or several closed paths for the flow of current. An elementary single mesh network, in…
