Kirchhoff's Current and voltage law, kvl and KCL law, what is kvl and KCL, important of Kirchhoff'law???

KIRCHHOFF'LAW , KVL & KCL

Kirchhoff's laws mainly dependent on the law of conservation of charge.
Kirchhoff's law is given by great scientist Kirchhoff by using law of conservation of charge.

THERE ARE TW
O LAW GIVEN BY GREAT scientist...
   1) kirchhoff's current law(KCL)
   2) kirchhoff's voltage law (KVL)

1) KIRCHHOFF'S CURRENT LAW(KCL)

             According to kirchhoff's current law at any junction in an electric circuit the total current flowing towards that junction is equal to the total current flowing away from the junction,it means..





      Total flow of current in any direction is equal to the total flow of current in opposite directions at any junction.

I1 +I2 = I3 + I4 + I5 or

I1 +I2 - I3 - I4 - I5 = 0

      
KIRCHHOFF'S VOLTAGE LAW (KVL)
       
                According to kirchhoff's voltage law in any closed loop in a Electric network ,the algebraic sum of the voltage drops means products of current and resistance taken around the loop is equal to the resultant emf(resultant voltage )acting in that loop.
 
Presentation of KVL

           E1 - E2 =IR1 + IR2 + IR3

RRB GROUP 'D' का जल्द ही post निकलने वाली है। कब पोस्ट निकलने की संभावना हैं? दोस्तों संभावना है की आरआरबी ग्रुप डी का वेकेंसी जल्द ही निकलने वाली है ? दोस्तों RRB NTPC का परीक्षा जल्द ही समाप्त होने वाली है । दोस्तों सरकारी संस्थान का कहना है RRB NTPC ka परीक्षा 30 जुलाई को खत्म हो जाएगी।      उसके तदुप्रांत RRB Group D   की परीक्षा के लिए           जल्द ही डेट fixed करने की संभाना है। RRB GROUP D का vaccancy अनुमान अनुसार 30 जुलाई के बाद निकालने की सम्भावना है।

What is force , explanation of force , role of force in our daily life , important of force Definition of force :- force is a physical quantity that can change position of any object that means if any object in motion then we can change in rest and if any object in rest then we can change in motion. UNIT OF FORCE IS NEWTON DENOTED BY "N" . FORMULA OF FORCE                              F = ma         Other unit of force is kilogram meter per second square ( kgm/sec^2 )    Definition of 1 Newton                         The Newton is defined as when we applied any force to mass of 1kg and that is accelerated by 1 meter per second squared ( 1m/s^2 ) , Then that force is called 1 Newton.         From formula,                      F = ma     ...
