Question

1. what happens to current in a circuit when the resistance increases, and the voltage remains the same?

current will increase and then decrease.
current will increase.
current remains the same.
current will decrease.

Explanation:

Step1: Recall Ohm's Law

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

Step2: Analyze proportional relationship

When $V$ is constant, $I$ is inversely proportional to $R$.

Step3: Apply given condition

If $R$ increases and $V$ stays the same, $I$ must decrease.

Answer:

Current will decrease.
