Current Electricity question

2023 · 11 Apr · Shift 2 · Q70

JEE MainPhysicsCurrent ElectricityNumerical+4 / −1
Two identical cells each of emf 1.5 V1.5 \mathrm{~V}1.5 V are connected in series across a 10 Ω10 ~\Omega10 Ω resistance. An ideal voltmeter connected across 10 Ω10 ~\Omega10 Ω resistance reads 1.5 V1.5 \mathrm{~V}1.5 V. The internal resistance of each cell is ‾Ω\underline{\hspace{2cm}}\Omega​Ω.
