Kirchoff's Law

Kirchoff's Law



  • Kirchoff's gave two most famous laws in electrical world which is given below.
  1. Kirchoff's current law
  2. Kirchoff's voltage law

1. Kirchoff's current law


  • Statement

  • " Kirchoff's current law state that the algebraic sum of all current meeting at a point or node in any electrical circuit is zero."
  • Mathematically
  • I1 + I2 - I3 + I4 - I5 = 0
  • Kirchoff's current law known as KCL

2. Kirchoff's voltage law

  • Statement
  • " Kirchoff's voltage law state that the algebraic sum of voltage across all elements in loop is zero. "
  • Mathematically
  • V12 + V23 + V34 + V41 = 0
  • Kirchoff's voltage law know as KCL.

MarX Generator

MarX Generator | High voltage pulse generator Marx Generator - High voltage pulse generator What is MarX Generator? Marx Generator is Electrical circuit which used for generate high voltage pulse. Marx generator is same as like voltage multiplier circuit. First watch the video of marx generator.. Marx Generator produce high voltage Spark as like lightning. Now learn how to make marx generator... Circuit Diagram of marx generator circuit is shown in below image. Circuit Diagram of marx Generator Here, First capacitor are connected in parallel. When DC supply is applied, capacitors charge through resistor by voltage Vc. Spark gaps use as a switch, Here first spark gap voltage is greater than the voltage Vc. So spark gaps are behave as a open circuit during capacitor charge. Now to generate high voltage pulse, The first spark gap need to be breakdown. So, By breakdown spark gap will be short circuit an...

Variable Inductance Transducer | Classification Of Variable Inductance Transducer

Variable Inductance Transducer | Classification Of Variable Inductance Transducer Variable Inductance Transducer | Classification Of Variable Inductance Transducer These are based on a change in the magnetic characteristic of an electrical circuit in response to a measurand which may be displacement, velocity, acceleration etc. Variable inductive transducer may be classified as follows: 1.Self-generating type In this type voltage is generated because of the relative motion between a conductor and a magnetic field. These may be further classified as follows: (A)Electromagnetic type (B)Electrodynamic type (C)Eddy current type 2.Passive type In this type the motion of an object results in change in the inductance of the coils of the transducer. These may be further classified as follows: (A)Variable reluctance (B)Mutual inductance (C)Differential transfer type 1.Self-generating Type (A)Eleotromagnetic t...
