Question

Which of the following is correct relative to Ohm's law?

1) I = R / V
2) Current is directly proportional to the voltage.
3) R = V + I
4) The more intense the stimulus, the more voltage changes.

Answer 1

Ohm's law states that current is directly proportional to voltage and inversely proportional to resistance in an electrical circuit, represented by the equation V = IR.

Step-by-step explanation:

According to Ohm's law, the correct statement related to the relationship between current (I), voltage (V), and resistance (R) in a simple electrical circuit is that the current is directly proportional to the voltage. Specifically, Ohm's law is expressed as V = IR, which means that voltage equals current multiplied by resistance.

Therefore, when looking at how current depends on resistance, we understand that current is inversely proportional to the resistance, not directly proportional or proportional to the square of the resistance. An increase in resistance will lead to a decrease in current, assuming that the voltage remains constant.

Ohm's law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across the conductor, while the resistance (R) remains constant. The mathematical expression of Ohm's law is given by the formula I = V / R. Therefore, the correct statement relative to Ohm's law is option 1, I = R / V, as it represents the correct formula.
