Below a reading of 200 counts, add 10 counts. Figure 6: Accuracy of the meter for ac and dc current 45 Resistor Colour Code The resistance of a resistor is indicated by four coloured bands, as shown in Fig (7). Reading from left to right, the ﬁrst two bands represent the ﬁrst two digits, the third the multiplier and the fourth band, which is gold or silver, represents the tolerance of the resistor. A B C D Figure 7: Four coloured bands enable the resistance to be determined Denoting the bands by A, B , C and D, then the value of the resistor (in Ω) is AB × 10C where the numerical values of A, B and C are given by the colour code in the table. 6 Colour Value black brown red orange yellow green blue violet grey white 0 1 2 3 4 5 6 7 8 9 Multiplier 0 10 = 1 101 = 10 102 = 100 103 = 1000 104 105 106 107 108 109 Tolerance (D) gold ±5% silver ±10% no band ±20% For example, if the bands on a resistor are coloured yello...
