Answer

Answer:

A. goes down.

Explanation:

Step1: Recall Ohm's Law

$I=\frac{V}{R}$, where $I$ is current (amperage), $V$ is voltage, and $R$ is resistance.

Step2: Analyze the situation

Given $V$ is constant. Let $V = k$ (constant). Then $I=\frac{k}{R}$. As $R$ increases, the value of $\frac{k}{R}$ (i.e., $I$) decreases.
