Or you can Identify and check its value by  using Resistance Tester...<img src="http://lh4.ggpht.com/_8JZhVVmpICU/S7-B8-hRqHI/AAAAAAAAAI0/buv9sU9iEaE/smt%20resistor.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />In Schematic Diagram  Its Original value where indicated: For Example:Resistances less than 1000 ohms or 1K  with ''R'' indicated in the middle indicates a decimal point like:4R7 = 4.7Ω 2R2 = 2.2Ω and the rest just like how it does indicated like:100Ω  = 100  ohms220Ω  = 200 ohmsand up4.7K   = 4.7 kiloohms The Printed SMD ResistorZero  ohm resistors Surface mounted resistors are printed with numerical  values in a code related to that used on axial resistors. <img src="http://lh4.ggpht.com/_8JZhVVmpICU/S7-B9aSzx9I/AAAAAAAAAI4/MspvYGRA1Ec/SMT%20resistor%202.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Standard-tolerance  Surface Mount Technology (SMT) resistors are marked with a three-digit  code, in which the first two digits are the first two significant digits  of the value and the third digit is the power of ten (the number of  zeroes). For example:334     = 33 × 10,000 Ω = 330 kΩ222     = 22 × 100 Ω = 2.2 kΩ473     = 47 × 1,000 Ω = 47 kΩ105     = 10 × 100,000 Ω = 1 MΩResistances less than 100 ohms are written: 100, 220, 470. The final  zero represents ten to the power zero, which is 1. For example:100     = 10 × 1 Ω = 10 Ω220     = 22 × 1 Ω = 22 ΩResistances less than 10 ohms have 'R' to indicate the position of the decimal point (radix point). For example:4R7     = 4.7 Ω0R22     = 0.22 Ω0R01     = 0.01 ΩPrecision resistors are marked with a four-digit code, in which the  first three digits are the significant figures and the fourth is the  power of ten. For example:1001     = 100 × 10 ohms = 1 kΩ4992     = 499 × 100 ohms = 49.9 kΩ1000     = 100 × 1 ohm = 100 Ω"000" and "0000" sometimes appear as values on surface-mount zero-ohm links, since these have (approximately) zero resistance.</blockquote>
