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
