In the following Wheatstone bridge `P//Q = R//S`. If key `K` is closed, then the galvanometer will show deflection

In the following Wheatstones bridge P//Q=R//S . If key K is closed then the galvanometer will show deflection

The Wheatstone's network is shown in the figure. If the key K is closed, then the galvanometer will

Two inductors of self inductances L_(1) and L_(2) and of resistances R_(1) and R_(2) (not shown) respectively are conneted in the circuit as shown. At the instant t = 0, key k is closed. Obtain an expression for which the galvanometer will show zero deflection at all times after the key is closed.

In the circuit, shown in figure. R=5000Omega . If key K_1 is closed, galvanometer shows a deflection of 30 scale division. On closing key K_2 and making S=20Omega , the deflection of galvanometer reduces to 15 division. The resistance of galvanometer is

Figure shows a balanced Wheatstone's bridge (1) If P is slightly increased, the current in the galvanometer flow from A to C. (2) If P is slightly increased, the current in the galvanometer flows C to A. (3) If Q is slightly increased, the current in the galvanometer flows from C to A. (4) If Q is slightly increased, the current in the galvanometer flows from A to C.

In a Wheatstone's bridge P=100Omega, Q=1000Omega and R = 40Omega . If the galvanometer shows zero deflection, determine the value of S.

The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false. Assertion: Potentiometer is the practical form of wheatstone bridge. Reason:In balanced position of wheatstone bridge, the galvanometer shows large deflection.
