In a metre bridge [Fig. 3.27], the balance point is found to be at 39.5 cm from the end A, when the resistor Y is of `12.5 Omega` Determine the resistance of X. Why are the connections between resistors in a Wheatstone or meter bridge made of thick copper strips?:

Why are the connections between the resistors in a meter bridge made of thick copper strips?

In a metre bridge [Fig. 3.27], the balance point is found to be at 39.5 cm from the end A, when the resistor R is of 12.5 Omega . Determine the balance point of the bridge above if R and S are interchanged. :

In a metre bridge, the balance point is found to be at 39.5 cm from the end A, when the resistor Y is of 12.5 Omega . Determine the resistance of X. Made of thick copper strips? Determine the balance point of the bridge above if X and Y are interchanged. What happens if the galvanometer and cell are interchanged at the balance point of the bridge ? Would the galvanometer show any current?

With two resistance R_1 and R_2 (>R_1) in the two gaps of a metre bridge the balance was found to be 1/3 m from the zero end. When a 6 Omega resistance is connected in series with the smaller of the two resistance, the point is shifted to 2/3 m from the same end, then R_1 and R_2 Find the resistance of the two wires.

In a meter bridge experiment null point is obtained at 20 cm. from one end of the wire when resistance X is balanced against another resistance Y. If XltY, then where will be the new position of the null point from the same end, if one deicdes to balance a resistance of 4 X against Y?

Two resistances are connected in the two gaps of a meter bridge. The balance point is 20 cm from the zero end. When a resistance 15 Omega is connected in series with the smaller of two resistance, the null point shifts to 40 cm. The smaller of the two resistance has the value.

In comparing the resistance of two cells P and Q with a sides wire bridge, a balance point is obtained when the sliding contact is 30 cm from the zero end of the wire. The resistances P and Q are interchanged and the balance is obtained at 120 cm from the same emf. Find the ratio of the resistance P and Q and the length of the bridge wire

Figure shows potentionmeter circuit for comparison of two resistances. The balance point with a standard resistor R=10.0Ω is found to be 58.3 cm, while that with the unknown resistance X is 68.5 cm. Determine the value of X. What would you do if you failed to find a balance point with the given cell of emf E?
