If each resistance in the figure is of $9 \mathrm{\Omega }$, then reading of Ammeter is

Two resistors of resistance $R_1$ and $R_2$ having $R_1>R_2$ are connected in parallel. For equivalent resistance $R$, the correct statement is

The potential difference between points $A$ and $B$ of adjoining figure is

Seven resistances are connected as shown in the figure.

The equivalent resistance between $A$ and $B$ is

What is the equivalent resistance between the points $A$ and $B$ of the network?

A uniform wire of resistance $9 \mathrm{\Omega }$ is cut into $3$ equal parts. They are connected in the form of an equilateral triangle $ABC$. A cell of emf $2 \mathrm{V}$ and negligible internal resistance is connected across $B$ and $C$. Potential difference across $AB$ is

In the figure shown the current flowing through $2R$ is 

The equivalent resistance between the points $A$ and $B$ is
