Question

1. according to ohms law, what must increase if resistance is decreased?- voltage- potential difference- ohms- current

Explanation:

Ohm's law is defined by the relationship $I = \frac{V}{R}$, where $I$ is current, $V$ is voltage (also called potential difference), and $R$ is resistance (measured in ohms). When voltage is held constant, current and resistance have an inverse relationship: if resistance decreases, current must increase to maintain the equality. Voltage/potential difference is the independent variable here, and ohms are the unit of resistance, so they do not increase when resistance decreases.

Answer:

current
