KIRCHHOFF’SVOLTAGELAW
Kirchhoff’s	
  laws	
  are	
  a	
  brilliant	
  reflecAon	
  of	
  
fundamental	
  laws	
  like	
  conservaAon	
  of	
  
charge	
  and	
  energy	
  in	
  the	
  context	
  of	
  
electrical	
  circuits.	
  Kirchhoff’s	
  Voltage	
  law	
  
(KVL)	
  states	
  that	
  the	
  algebraic	
  sum	
  of	
  the	
  
potenAal	
  differences	
  in	
  a	
  closed	
  circuit	
  
must	
  be	
  zero.	
  To	
  verify	
  this	
  law,	
  we	
  will	
  
make	
  a	
  circuit	
  in	
  which	
  mulAple	
  LEDs	
  and	
  a	
  
resistor	
  is	
  connected	
  in	
  series.	
  When	
  the	
  
circuit	
  is	
  complete,	
  the	
  voltage	
  is	
  measured	
  
across	
  each	
  LED	
  and	
  resistor	
  through	
  a	
  
mulAmeter.	
  It	
  was	
  observed	
  that	
  on	
  adding	
  
the	
  individual	
  voltages	
  across	
  each	
  
component,	
  the	
  sum	
  is	
  approximately	
  
equal	
  to	
  the	
  baRery	
  voltage	
  (Source).	
  This	
  
establishes	
  the	
  KVL.
