# The wheatstone bridge showing in Fig. Here, gets balanced when the carbon resistor used as R1 has the colour code (Orange, Red, Brown). The resistors R 2 and R4 are 80and 40, respectively. Assuming that the colour code for the carbon resistors gives their accurate values, the colour code for the carbon resistor, used as R3 would be: (a) Red, Green, Brown (b) Brown, Blue, Brown (c) Grey, Black, Brown (d) Brown, Blue, Black
