$(a)$ In the circuit shown connect a nichrome wire of length ${ }^{\prime \prime} L^{\prime \prime}$ between points $X$ and $Y$ and note the ammeter reading.
$(i)$ When this experiment is repeated by inserting another nichrome wire of the same thickness but twice the length $(2 L),$ what changes are observed in the ammeter reading ?
$(ii)$ State the changes that are observed in the ammeter reading if we double the area of cross-section without changing the length in the above experiment. Justify your answer in both the cases.
$(b)$ "Potential difference between points $A$ and $B$ in an electric field is $1\, V^{\prime \prime} .$ Explain the statement.
