Ohm 4 Band Resistor Color Code. The 4 color bands on the left side are grouped together to represent the resistance value of a resistor and the 5 th color band on the right side indicates the tolerance of the resistor. Resistor color code band 1 band 2 band 3 22 ohm r22 red red silver 27 ohm r27 red purple silver 33 ohm r33 orange orange silver 39 ohm r39 orange white silver 47 ohm r47 yellow purple silver notation tolerance 56 ohm r56 green blue silver 68 ohm r68 blue gray silver 82 ohm r82 gray red silver 1 0 ohm 1r0 brown black gold 1 1 ohm 1r1 brown brown.
Similar to the 3 band resistor the first two bands always give the first 2 digits of the resistance value. The 4 color bands on the left side are grouped together to represent the resistance value of a resistor and the 5 th color band on the right side indicates the tolerance of the resistor. 4m7 4 7m ohm resistor colour code.
680r 680 ohm resistor colour code.
Since this is a 4 band resistor the resistance color code wheel can be used to find the resistance value of a 5 band resistor so the third digital wheel is not used in this case. Brown black brown gold the color code for the four bands 100 ohm resistor is brown black brown gold. 4 band colour code system. The 4 band resistor color code is the most commonly used resistor.
