A battery of $emf$ $10\,V$ is connected to resistances as shown in the figure. The potential difference between $A$ and $B,\,\,(V_A -V_B)$ is ................ $V$
A battery of $6\, volts$ is connected to the terminals of a three meter long wire of uniform thickness and resistance of the order of $100\,\Omega $. The difference of potential between two points separated by $50\,cm$ on the wire will be .......... $V$
Two cells when connected in series are balanced on $8\;m$ on a potentiometer. If the cells are connected with polarities of one of the cell is reversed, they balance on $2\,m$. The ratio of $e.m.f.$'s of the two cells is
