current through the circuit \(i = \frac{{2.4}}{{100}}\,A\)
\(P.D.\) across combination of voltmeter and \(100\,\Omega\) resistance \( = \frac{{2.4}}{{100}} \times 50 = 1.2\,V\)
Since the voltmeter and \(100\,\Omega\) resistance are in parallel, so the voltmeter reads the same value i.e. \(1.2\,V.\)
