What Is Voltage Or Potential Difference ?

               What Is Voltage Or Potential Difference ?

Answer-: Voltage  or Potential Difference is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).



     Common symbols: V, ∆V, U, ∆U  

        Dimension: M L2 T−3 I−1

Derivations from other quantities: Voltage = Energy / charge

What Is An Inductor?

Image
                     What Is An Inductor? An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction. The Inductor Basically Used For Increase Or  Decrease Of Current                          One Example On Current Increasing-:  You Are See Here Is A Battery , A  bulb,A coil Of Wire(Inductor) Around A Piece Of Iron(Yellow Coloured) And A Switch The Coil Of Wire Is An Inductor. If You Were To Take Out The Inductor From This Circuit You Get A Normal Light. But When You Connect The Inductor To This Circuit  And Close The Switch The bulb Burns Brightly And Then Quickly Goes Out. It Occur Because The Current Increase During Connect Of Inductor. Example Of Current Decreasing-: A  choke coil  is an inductance  coil  of very small resistance

What Is Transformer?

Image
                                             What Is   Transformer? A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits without change of frequency. A  transformer  consists of two electrically isolated coils and operates on Faraday's principal of “mutual induction”, in which an EMF is induced in the  transformers  secondary coil by the magnetic flux generated by the voltages and currents flowing in the primary coil winding. Working Principle -: The  operation principle  of the  single - phase transformer  is: the AC voltage source injects the AC current through the  transformer  primary winding. ... Thus the voltage is induced in the secondary winding with the same frequency as the voltage of the primary side. The induced voltage value is determine by Faraday's Law Uses -:  Transformers  are most commonly used for increasing low AC voltages at high current (a step-up  transformer ) or decrea

HOW TO MAKE ARDUINO UNO BASED PROJECTS ? At First I Recommend To All My Readers That They Should Be Use A Computer OR Laptop. I Will Be Tell You How Can Upload Programming On Arduino Nano On Another Post. Today I Talk About Arduino Uno Based Projects  At First You Should Go To Arduino's Official Website (https://www.arduino.cc/en/Main/Software)  Here You Can Download Arduino IDE Software And Install It On Your PC. If You Are New On This Project You Should Start From Blink The LED Light . Hardware Required Arduino or Genuino Board optional  1xLED 1x220 ohm resistor If you want to lit an external LED with this sketch, you need to build this circuit, where you connect one end of the resistor to the digital pin correspondent to the  LED_BUILTIN  constant. Connect the long leg of the LED (the positive leg, called the anode) to the other end of the resistor. Connect the short leg of the LED (the negative leg, called the cathode) to the GND. In the diagram below we show an UNO board. The
