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…
Zero Reference Level in Electronics Engineering: Zero Reference Level - In order to avoid errors in the measurement of different voltages in an electronic circuit, it is imperative to select some common point, known as…
What is Capacitor in Electronics?: What is Capacitor in Electronics? - Capacitor is a two-terminal element that has the capability of charge storage and, consequently, energy storage. The stored energy can be fully retrieved. The…
What is Inductor in Electronics? An inductor has been defined as a physical device which is capable of storing energy by virtue of a current flowing through it. An Inductor in Electronics is a circuit…
