.In a balanced Wheatstone bridge the resistors across the terminals AB,BC,CD and DA are replaced with inductors of 10 H, 20 H, 30 H and 40 H with internal resistances of xΩ,2xΩ and 3xΩ and 4xΩ respectively, and it is fed with DC source. B1.1. Examine if the bridge can be balanced by selecting the appropriate value of x, Justify. B1.2. If an inductor of value L Henry with an internal resistance of rΩ is connected across the terminals BD; formulate the expression for balanced bridge condition B1.3. If an ideal inductor of value L Henry is connected across the terminals BD; formulate the expression for balanced bridge condition. Justify.
