Write the colour code of a carbon resistor of resistance 23 kilo ohms.

Colour code of carbon resistor of resistance $23\mathrm{k\Omega }.\text{ Resistance }=23\times {10}^3\mathrm{\Omega }$
$2\to \text{ Red, }3\to \text{ Orange, }{10}^3\to \text{ Orange }$

Colour code of carbon resistor is Red, orange, orange.
