Question

if voltage stays the same, but resistance goes up, what happens to amperage? select one: a. goes down. b. goes up. c. stays the same. d. amperage can not change unless voltage changes.

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.

Answer:

A. goes down.
