Question

To verify Ohm's law, a student connects the voltmeter across the battery as, shown in the figure. The measured voltage is plotted as a function of the current, and the following graph is obtained :
If V₀ is almost zero, identify the correct statement :

The value of the resistance R is 1.5 $\Omega $

The emf of the battery is l.5 V and its internal resistance is 1.5 $\Omega $

The emf of the battery is l.5 V and the value of R is 1.5 $\Omega $

The potential difference across the battery is 1.5 V when it sends a current of 1000 mA
