Question

When the resistance in a circuit remains constant, how are the voltage and current related?
The current doubles when the voltage doubles because they are directly proportional.
The current doubles when the voltage doubles because they are inversely proportional.
The current is cut in half when the voltage doubles because they are directly proportional.
The current is cut in half when the voltage doubles because they are inversely proportional.

    Answer:

    The current doubles when the voltage doubles because they are directly proportional.

    Explanation:

    When relating resistance (R), current (I), and voltage (V), we use Ohms Law

    V = I R

    As a simple example, if we plug some random values into the equation we can see this in action

    V = 6V

    I = 2A

    R = 3Ω

    6 = 2 * 3

    Now if we keep the resistance the same but double the voltage, the current will have to double to show the change

    12 = 4 * 3

    So, The current doubles when the voltage doubles because they are directly proportional.
