PHYSICS INVESTIGATORY PROJECT ON

LOW RESISTANCE PATH USING A DIODE

Do  you  know  that  the  current  flowing  in  a  circuit  is  selecAve  in  nature?  If  there  are  two  paths  for  a  current,  it  will  choose  the  one  with  a  lower  

resistance.  Using  this  circuit,  you  will  analyze  how  it  actually  happens.

In  this  project,  you  will  need  a  breadboard,  a  diode,  a  resistor,  an  LED  and  a  few  connecAng  wires.  The  connecAons  are  made  such  that  the  resistor  is  connected  to  the  parallel  combinaAon  of  the  LED  and  the  diode.  Upon  the  compleAon  of  the  

circuit,  the  LED  starts  glowing.  In  this  case,  the  LED  is  forward  biased  and  the  diode  is  reverse  biased.  

However,  if  the  connecAons  are  reversed,  the  LED  

turns  OFF.  In  this  case,  both  the  LED  and  the  diode  are  forward  biased  and  sAll  the  LED  does  not  glow.  

The  reasoning  of  the  phenomena  is  inferred  by  doing  the  currents’  path  analysis  and  analyzing  the  threshold  voltages  at  which  the  LED  and  the  diode  become  forward  biased.
