Production Management | Objectives, Functions, Production Planning & Control
Introduction Production management is the practice of overseeing and controlling a company's operations to efficiently create the goods and services it intends to produce. This involves planning, coordinating, and managing…
Economic Laws | Types, Features or Nature
Introduction Like all other sciences, economics collects facts and undertakes systematic study. The facts are analyzed and conclusions are drawn. These conclusions establish a causal relationship between the concerned points.…
Display Devices | LCD, LED, Seven Segment, Sixteen Segment
Display Devices A display device serves as an output tool that visually conveys information. The display system is the ultimate connection between a measuring process and the user. In instrumentation…
Rotating Magnetic Field | Mathematical Analysis and Condition for Generation
Introduction A rotating magnetic field is a particular magnetic field created by using coils with multiple electrical phases (like three phases in many cases) and running electrical currents through them.…
Demand Forecasting | Features, Uses, Purpose, and Methods
A forecast, particularly in the context of demand forecasting, is a prediction or estimation of a future event that is most likely to happen under given conditions. In a world…
Starting and Speed Control Methods of 3-Phase Induction Motors
Introduction A three-phase induction motor has a kind of electrical "resistance" when it starts, which makes it draw too much electrical current when you turn it on. This can be…
Motor Braking | Types, Advantages, and, Applications
Introduction Electric braking provides a more consistent and controlled way to rapidly stop a running motor compared to mechanical braking, which relies on the condition and quality of brake shoes…
Losses and Efficiency Of D.C. Machines
Introduction Electric machines transform energy. Motors change electricity into motion, while generators turn motion into electricity. During this process, energy isn't perfectly converted; some is lost. These losses, like heat,…
D.C. Machine | Types, Losses, and Applications
Introduction DC machines come in two main types: DC motors and DC generators. They're a lot like AC machines but also handle AC currents and voltages. Despite this, they provide…
Incandescent lamps | Types, Advantages, and Applications
Introduction Heat is produced when an electric current is passed through a wire, which raises its temperature. At low temperatures, only heat (I.R. radiations) is produced. At high temperatures, light…
