Wheatstone Bridge

The percentage error in measuring resistance with a meter bridge can be minimised by adjusting the balancing point close to

Find (a) Equivalent resistance (b) and current in each resistance.

In the circuit shown, calculate the reading on the ammeter.

In the given figure, calculate the equivalent resistance between points A and B.

Figure shows an unbalanced Wheatstone bridge. What is the direction of conventional current between $B$ and $D$?

If the central resistance is $15 \mathrm{\Omega }$, then the equivalent resistance between $A$ and $B$ will be

Find the equivalent resistance between $X$ and $Y$.

Find the equivalent resistance between $X$ and $Y$.

The effective resistance between points P and Q of the electrical circuit as shown in the figure is

 

In a metre bridge experiment, null point is obtained at $20 \mathrm{cm}$ from one end of the wire when resistance $X$ is balanced against another resistance $Y$. If $X<Y$, then there will be the new position of the null point from the same end, if one decides to balance a resistance of $4 X$ against $Y$

In a Wheatstone bridge the branch resistances are as shown in the following circuit diagram. What will be the value of $X$ in balancing the condition of the Wheatstone bridge?

What will be the value of resistance $R$ for the network shown in the figure so that the current in ammeter may be zero.

On interchanging the position of battery and galvanometer in Wheatstone bridge respectively the new balance point:
