ELECTRICITY MAGNETISM

MAGNETISMThere are several relationships between electricity and magnetism. We will explore them one by one. The first relationship we will discuss is how current flowing through a wire creates a magnetic field. A steady current creates a steady magnetic field like that created by a magnet. Electro-Magnet We can create an electro-magnet by wrapping many turns of wire on a core, then causing an

BOOST CONVERTER

A boost converter is a DC-to-DC power converter with an output voltage greater than its input voltage. It is a class of switched-mode power supply (SMPS) containing at least two semiconductor switches (a diode and a transistor) and at least one energy storage element, a capacitor or inductor. The boost converter is also called as step-up converter.

PIR motion sensors

PIR Sensor





 


     
PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. 
They are small, inexpensive, low-power, easy to use and don't wear out. 

For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric",

What do you meant by earthing?

Earthing is a safety device used to prevent a shock due to leakages arising from weak insulation, breaking of the element or otherwise. 

The metal bodies of appliances handled like the electric iron, kettle or refrigerator must be earthed, that is, connected to a pipe leading deep into the earth on to a metal plate.

In case the metal body becomes live, the circuit is completed through the

Perceptron- Artificail Neural Networks

Neural Networks


Artificial neural networks are composed of interconnecting artificial neurons (programming constructs that mimic the properties of biological neurons). 

Artificial neural networks may either be used to gain an understanding of biological neural networks, or for solving artificial intelligence problems without necessarily creating a model of a real biological system.
