If in a meter bridge experiment, the balancing length `l` was 25 cm for the situation shown in the figure. If the length and diameter of the of wire of resistance R is made half, then find the new balancing length in centimetre is

In a meter bridge experiment, resistances are connected as shown in figure. The balancing length l_(1)=55cm . Now, an unknown resistance x is connected in series with P and the new balancing length is found to be 75 cm. What is the value of The value of 11x (in ohm)? (Given, P=4Omega )

One ideal cell is used to drive current in a metre bridge circuit. In an experiment x is the balancing length obtained. If we replace the wire of the metre bridge with another wire of material having more rsistivity and lesser diameter, the new balancing length will be

In the metre bridge, the balancing length AB =l=20 cm. The unknown resistance X is equal to

In a metre bridge experiment l_(x) and l_(r) are the balancing lengths and R is known resistance then unkown, resistance is given by

In the figure shown wire AB has a length of 100 cm and resistance 8Omega . Find the balance point length l .

In the figure shown wire AB has a length of 100 cm and resistance 8Omega . Find the balance point length l .

If the resistance of potentiometer wire is 15r then calculate the balance length l

Statement I: In the meter bridge experiment shown in figure, the balance length AC corresponding to null deflection of the galvanometer is x. If the radius of the wire AB is doubled, the balanced length becomes 4x. Statement II: The resistance of a wire is inversely proportional to the square of its radius.
