(d) Resistance between $A$ and $B$ $ = \frac{{1000 \times 500}}{{(1500)}} = \frac{{1000}}{3}$
So, equivalent resistance of the circuit
${R_{eq}}$ $ = 500 + \frac{{1000}}{3} = \frac{{2500}}{3}$
Current drawn from the cell
$i = \frac{{10}}{{(2500/3)}} = \frac{3}{{250}}A$
Reading of voltmeter i.e.
potential difference across $AB = \frac{3}{{250}} \times \frac{{1000}}{3} = 4\,V$
