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:
(A) The potential difference across the battery is 1.5 V when it sends a current of 1000 mA.
(B) The emf of the battery is 1.5 V and the value of R is 1.5 Ω
(C) The emf of the battery is 1.5 V and its internal resistance is 1.5 Ω
(D) The value of the resistance R is 1.5 Ω

Answer 1

the correct answer is

The emf of the battery is 1.5 V and its internal resistance is 1.5 Ω.
