PHYSICS INVESTIGATORY PROJECT ON

KIRCHHOFF’S VOLTAGE LAW

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.

Have  a  look  at  our  Project  Kit!

CoolJunk   is   India's   fastest   growing  DIY   (do-­‐it-­‐yourself)   kits   company   focused   on   project-­‐based   learning   in  science,   engineering   and   technology.  Having   20,000   users   in   India,  US,   Singapore,   Middle   East   and   New  Zealand,  the  CoolJunk  kits  are  known   for  quality,  innovaAon   and  high  producAon  value.  CoolJunk  has  been  featured   in   naAonal   and   internaAonal   journals   including   Wallstreet,   Yourstory,   Hindu   Business   Line,  NextBigWhat  and  was  tagged  as  the  coolest  Indian  start-­‐up  in  IAN  Bootcamp-­‐2011.
