    if you want help  you need to state the colors from left to right of EACH resistor ...... on the screen, they are all  gray stripes ! 

    BBROYGBVGW       is the color scheme  each letter is a color  from  0  to  9

       Black Brown Red Orange Yellow Green Blue Violet Gray White

      memory aid:      Better Be Right Or Your Great Big Vacation Goes Wrong 

         after   White  comes      Gold     Silver     None (no stripe)  .... these colors  are  for   % tolerance / error    beyond the regular colors  used in 4th stripe.

     

    G = +/- 5%    S = +/- 10%      No  stripe = +/-  20%

     usually   Tolerance  stripe is  Brown  1%,    Red 2%    or  Gold  Silver  None

    first  3  stripes are  values    ...  2 digits  and multiplier [ like 100, 1000, etc.. ]   ,  4th is tolerance

    EX.   Br  R  Y        R          means   1 2    add 4 zeros [ mult by 10,000 ]    which gives    120000  ohm    .......  last  red  --> 5%  tolerance   ( 5% of 120000 )
