Converting Between Number Systems
It is often necessary to convert values written in one number system to another. The simplest way is to reach for your calculator or use a conversion app. from the…
Resistor Parameters
Not only Ohms When considering resistors, resistance is not the only important thing to think about. Like any other component there are a number of important things to consider. Here…
Resistors
Resistor Construction Resistors are components used to resist the flow of electric current and have a stated value of RESISTANCE. • Many types of resistors are used having different uses…
Types Of Loads
A device which taps electrical energy from the electric power system is called a load on the system. The load may be resistive (e.g., electric lamp), inductive (e.g., induction motor),…
L.T. Cables
L.T. (Low Tension) cables are widely used for low voltage (1.1kV). These cables must have proper protection from water, corrosion and mechanical strength must be high. These cables must sustain…
Vectors Basics
[vc_row][vc_column width="2/3"][vc_column_text]Vector analysis is a mathematical subject which is much better taught by mathematicians than by engineers. Vector analysis is mathematical shorthand. It has some new symbols, some new rules,…
Vector Coordinate System
[vc_row][vc_column width="2/3"][vc_column_text]In order to describe a vector accurately, some specific lengths, directions, angles, projections, or components must be given. There are three simple methods of doing this, and about eight…
Magnetic Circuits
[vc_row][vc_column width="2/3"][vc_column_text] Introduction Magnetic Circuits offer, as do electric circuits, a way of simplifying the analysis of magnetic field systems which can be represented as having a collection of discrete…
Losses in a DC Machine
[vc_row][vc_column width="2/3"][vc_column_text]Motors convert electrical power (input power) into mechanical power (output power) while generators convert mechanical power (input power) into electrical power (output power). Whole of the input power cannot…
