Find the value of the unknown resistance `X`, in the following circuit if no current flows through the arm AO from the battery of `6V` and negligible internal resistance. Also find the Current flowing from the battery. |

Answer» Correct Answer - `1A` When no current flow through the arm `AO` the wheatstone bridge in balanced .Then `(2)/(X) = (3)/(6) or X = 4 Omega ` Total resistance of circuit `R = ((2 + 4) xx (3 + 6))/((2 +n 4) + (3+ 6)) + 2.4 = 6 Omega` Current is circuit `I = (epsilon)/(R ) = (6)/(6) = 1A` |
