The Wheatstone bridge shown in Fig. here, gets balanced when the carbon resistor used as 
has the colour code (Orange, Red, Brown). The resistors 
and 
are 
and 
, respectively. Assuming that the colour code for the carbon resistorsgives their accurate values, the colour code for the carbon resistor, used as 
, would be:
