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 correct answer is the current doubles when the voltage doubles because they are directly proportional.

Explanation-

From ohm's law we know that at constant temperature and pressure, the current flowing through a wire is directly proportional to the potential difference across the two ends of a conductor.

Mathematically V ∝ I

                       ⇒ V = IR

Here, R is called as the resistance of the conductor, V is the voltage, and I is the current.

As per the question, the resistance is kept constant.

Hence, if current is doubled in the circuit, then voltage is also doubled as current and voltage are directly proportional to each other.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
