Electrictrostatics of condcutors

Conductors have a lot of electrons almost in the range of 1029 per cubic m. So, subjecting conductors to an external field usually results in the rearrangement of the electrons such that the positive ions are away from the Electric field and the negative ones closer to the electric field. This gives rise to an induced electric field that grows on strength till it becomes equal to the external

Potential due to dipole

Electrostatic potential due to positive charge is q/4πεₒr and physically it requires work to bring another charge at position r to overcome the force of attraction. If unsupported the charge thus brought will be repelled and accelerated away. Similarly, for a negative charge, the potential is given by (-q)/4πεₒr and it means that we need to prevent a positive test charge from bumping

Tips for Isometric projection of machine blocks

Orthographic projection gives us views of objects from a particular direction only. Looking from the front, we get front elevation and from the top, we get a plan or the top view. The orthographic projection is complete in one direction only. To have an entire detail, we need to prepare at least three different views from three different directions. Still, for a quick reference, a pictorial view

noreply@blogger.com (Sureshiisj) — Thu, 7 Apr 2022 17:09:00 +0900

Chapter 2: Electrostatic Potential and Capacitance. Starting from the concept of electrical work, we establish the concept of electrostatic potential energy. This energy per unit charge is defined as the electric potential. We obtain an expression for the potential of a source charge by bringing a unit test charge from infinity to a location in the space. Similarly, using the geometry,

Isometric Scale

noreply@blogger.com (Sureshiisj) — Tue, 5 Apr 2022 22:14:00 +0900

An isometric scale is used for isometric projection. Most of the drawings on a plain sheet of paper are 2-dimensional. We can use three axes at 120o with each other to indicate three dimensions of an object. This generally helps in creating 3-dimensional drawings on a 2D plane. CBSE Class 12 has isometric scale construction as an essential construction skill. The steps of
