  Resistance  \Re*sist"ance\  (-ans),  n.  [F.  r['e]sistance,  LL 
  resistentia  fr  resistens  -  entis,  p.  pr  See  {Resist}.] 
  1.  The  act  of  resisting;  opposition,  passive  or  active.

  made  against  him  he  sent  away  all  his  forces.  --1. 
  Macc.  xi  38. 
 
  2.  (Physics)  The  quality  of  not  yielding  to  force  or  external 
  pressure;  that  power  of  a  body  which  acts  in  opposition  to 
  the  impulse  or  pressure  of  another,  or  which  prevents  the 
  effect  of  another  power;  as  the  resistance  of  the  air  to 
  a  body  passing  through  it  the  resistance  of  a  target  to 
  projectiles. 
 
  3.  A  means  or  method  of  resisting;  that  which  resists. 
 
  Unfold  to  us  some  warlike  resistance.  --Shak. 
 
  4.  (Elec.)  A  certain  hindrance  or  opposition  to  the  passage 
  of  an  electrical  current  or  discharge  offered  by 
  conducting  bodies.  It  bears  an  inverse  relation  to  the 
  conductivity,  --  good  conductors  having  a  small 
  resistance,  while  poor  conductors  or  insulators  have  a 
  very  high  resistance.  The  unit  of  resistance  is  the  ohm. 
 
  {Resistance  box}  (Elec.),  a  rheostat  consisting  of  a  box  or 
  case  containing  a  number  of  resistance  coils  of  standard 
  values  so  arranged  that  they  can  be  combined  in  various 
  ways  to  afford  more  or  less  resistance. 
 
  {Resistance  coil}  (Elec.),  a  coil  of  wire  introduced  into  an 
  electric  circuit  to  increase  the  resistance. 
 
  {Solid  of  least  resistance}  (Mech.),  a  solid  of  such  a  form 
  as  to  experience,  in  moving  in  a  fluid,  less  resistance 
  than  any  other  solid  having  the  same  base,  height,  and 
  volume.

  2:  any  mechanical  force  that  tends  to  retard  or  oppose  motion 
  3:  a  material's  opposition  to  the  flow  of  electric  current; 
  measured  in  ohms  [syn:  {electric  resistance},  {electrical 
  resistance},  {impedance},  {resistivity},  {ohmic  resistance}] 
  4:  the  military  action  of  resisting  the  enemy's  advance;  "the
