Question

The colour coded corbon resistance has
three bands. The bands from left are blue,
yellow and red the resistance is
1) 642 +20%
2) 640092+ 20%
3) 6420 +10%
4) 52000+10%​

Answer 1

Answer:

For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.
