Figure 3: Resistors with 4 bands, 5 bands and 6 bands of color code. 2) To practically study the color rings on resistors and read the resistance and tolerance values of various resistors using color code. Procedure i) Take some assorted resistors available in laboratory. Hold a resistor in your hand and read the color rings (bands) by referring to table T.1.1. ii) Read the color rings/bands on the resistors left to right one by one and record the ring color and its value in the table T 1.2 shown below. Note down the Nominal resistance value (R ) and tolerance of the resistor in the table. Nominal iii) Repeat the above procedure for few more resistors. iv) Write down your observation. 1st color 2nd color 3rd color 4th color 5th color Tolerance band band band band band in Value (R Nominal) in Ohms 1 2
