Answer

Explanation:

Step1: Calculate total voltage

The total voltage $V$ is the product of the number of batteries and the voltage of each battery. There are 4 batteries each with a voltage of 1.5 volts, so $V = 4\times1.5=6$ volts.

Step2: Use Ohm's law

Ohm's law is $V = IR$, where $V$ is voltage, $I$ is current and $R$ is resistance. We want to find $R$, so we can rewrite the formula as $R=\frac{V}{I}$. Given $V = 6$ volts and $I = 2.0$ amps, then $R=\frac{6}{2}=3$ ohms.

Answer:

C. 3.0 ohms
