Resistance of a carbon resistor determined from colour codes is $(22000 \pm 5\%)\ \Omega$. The colour of third band must be :
Answer: (C) Orange
$22000 = 22 \times 10^3$.
The first two bands give the digits $2, 2$ (red, red). The third band is the multiplier $10^3$, which is orange.
(The $\pm 5\%$ tolerance is the gold fourth band.)
