Answer

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 relationship

When $R$ is constant, $I$ is directly proportional to $V$ as $I$ increases when $V$ increases and vice - versa.

Step3: Consider the evidence in an activity

In an electrical activity, if we measure the current for different voltages while keeping the resistance fixed (e.g., using the same set of bulbs or resistive elements), we can observe that as the voltage provided by the battery is increased, the current in the circuit also increases. This is direct evidence that current is directly proportional to voltage when resistance is held constant.

Answer:

The evidence from an electrical activity where the resistance is kept constant and the voltage is varied to measure the corresponding current values supports the claim that current is directly proportional to voltage. For example, using a variable - voltage power source and a fixed set of resistors (like bulbs), when the voltage is increased, the brightness of the bulbs (which is related to the current) also increases, showing a direct proportionality.
