A 10 V battery with internal resistance1\Omega and a 15V battery with internal resistance 0.6\Omega are connected in parallel to a voltmeter
As the two cells oppose each other hence, the effective emf in closed circuit is 15 - 10 = 5 V and net resistance is 1 + 0.6 = 1.6 Ω (because in the closed circuit the internal resistance of two cells are in series.

Current in the circuit,
The potential difference across voltmeter will be same as the terminal voltage of either cell. Since the current is drawn from the cell of 15 V
