Question

if voltage remains constant and resistance decreases, current flow: a) increases b) decreases c) stays the same d) doubles

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is $I=\frac{V}{R}$, where $I$ is current, $V$ is voltage and $R$ is resistance.

Step2: Analyze the situation

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

Answer:

A. increases
