# 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 80 and 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
