  This 
  false 
  resistance 
  superposed 
  on 
  the 
  other 
  resistance 
  

   makes 
  the 
  electrical 
  resistance 
  of 
  alloys 
  greater 
  than 
  the 
  

   value 
  expected 
  from 
  the 
  simple 
  view 
  of 
  mixture. 
  If 
  we 
  

   suppose 
  the 
  molecules 
  of 
  an 
  alloy 
  to 
  be 
  distributed 
  in 
  every 
  

   direction 
  in 
  the 
  same 
  way, 
  then 
  only 
  the 
  third 
  part 
  of 
  the 
  

   doublets 
  will 
  oppose 
  the 
  current 
  flowing 
  in 
  a 
  certain 
  direction.

  The

  additional

  a
