How Induction heating works?|Eddy current heating|Hysteresis loss ENGINEERING IS AWESOME 2021-12-09 | Induction heating explained through 3D animation.And the role of eddy current loss and hysteresis loss in the heating process.INDUCTION HEATING:Induction heating is a non-contact heating process, where an alternating magnetic field induces eddy currents in the metal.Which in turn generate heat due to the metals resistance to the eddy currents.This type of heating suits better for metals which have high resistance.In addition to that ferromagnetic materials are quickly heated because of the hysteresis loss,which happens due to the magnetization and demagnetization.

Transformers explained | How increasing the voltage, decreases the current in a transformer? ENGINEERING IS AWESOME 2021-06-13 | #Transformers #electrical #engineeringTransformers can step-up or step-down AC voltage through electromagnetic induction.Its contains a primary coil, a secondary coil and a laminated soft iron core.It alters the voltage by altering the coil configuration.Eddy current losses are produced in a transformer.They are minimized by using a laminated core.In power system a transformer is used to transmit the power efficiently.In this video we will see all of these through 3D animations.You may find this video interesting: youtu.be/uW-M8eBHq9UView and subscribe to this channel: youtube.com/channel/UCJpRjLI9u7Ux1_IFlXNLfVg/featured
Inductors working principle | Current lagging behind voltage in an inductor. ENGINEERING IS AWESOME 2021-03-18 | Inductors , Inductance, current lag and back emf - all explained in one video. So how does an inductor work? A changing current creates a back EMF due to faradays law of induction.According to lenz law this opposes the incoming current.So current faces an opposition.All these explained in a detailed way through 3D animations.Found this video helpful?Consider checking out my other videos too!Transformers explained- youtube.com/watch?v=WAa31KsR12M&t=26sSubscribe to this channel through: youtube.com/c/engineeringisawesome/videos
Diodes Explained - Forward and Reverse biasing | Doping ENGINEERING IS AWESOME 2021-03-03 | Diodes are like electronic check-valve for current flow.That is ,it allows current flow in one direction, but blocks it in the other direction. When a diode's cathode is connected to a negative terminal of a power supply and its anode to a positive terminal, current flows through the diode.But when the polarity is altered, it blocks the current flow.This is due to the semiconductors which makeup a diode.The most common semiconductor is Silicon.It has four valence electrons which make bonds with the neighbouring atoms through covalent bonding.Now the silicon behaves like an insulator.But when an external energy in the form of voltage is applied to it, some electrons in the bond break, and become free electrons.Due to the availability of free electrons, now the silicon behaves like a conductor.This is why silicon is called a semiconductor. A process called doping is done to silicon, to improve conductivity. There are two types of doping called p type and n type doping.Phosphorous and boron impurities are used in p and n type doping respectively. A diode has three regions called p region ,n region and depletion region.When p region is connected to positive terminal and n region to negative terminal,the charges crush the depletion region. At 0.7 volts, the depletion region breaks and current flows through diode.This is called forward biasing of a diode.When the polarity is altered, the electrons and holes are attracted towards the terminals and depletion region widens .This blocks the current flow.This is called reverse biasing of a diode. This is how a diode works
