The relationship between current and resistance is described as what?

1. Equal

2. Based upon available power

3. Inversely proportional

4. Linear

The correct answer is: Inversely proportional

The relationship between current and resistance is described as inversely proportional according to Ohm's Law. Ohm's Law states that the current \( I \) through a conductor between two points is directly proportional to the voltage \( V \) across the two points and inversely proportional to the resistance \( R \). Mathematically, this is expressed as \( I = \frac{V}{R} \). This means that if the resistance increases while the voltage remains constant, the current will decrease. Conversely, if resistance decreases, the current will increase. This inverse relationship highlights how resistance affects the flow of electric current in a circuit, emphasizing that higher resistance hinders current flow, while lower resistance facilitates it. In contrast, describing the relationship as equal would imply that current and resistance change together at the same rate, which does not reflect how they interact based on voltage. Saying it is based upon available power introduces a different relationship that involves energy considerations but doesn't accurately capture the direct interaction between current and resistance. Lastly, while there is a linear relationship between current and voltage in Ohm's Law when resistance is constant, it is not linear between current and resistance; hence, this choice does not correctly represent their relationship.
