Problem: Write the condition of balance in a Wheatstone bridge. In the given Wheatstone bridge, the current in the resistor 3R is zero . find the value of R ,if the carbon resistor, connected in one arm of the beige, has the colour code sequence of red,red,and orange. The resistance of BC and CD arms, are now interchanged and another carbon resistor is connected in the place of R so that the current through the arm BD is again zero,write the sequence of colour band of this carbon resistor.
