I have a question about Ohm’s Law. For a given potential difference, Resistance and Current Intensity are inversely proportional right? Potential difference is directly proportional to the Resistance and the Current intensity right? :)))

Hi

AdorableApatosaurus7671,Thank you for your question!

To answer this question, we first need to look at Ohm's law to see the relationship between the current intensity, the voltage and the resistance :

$$ U = RI $$

Where:

• U : potential difference, also known as voltage (V)

• R : resistance (Ω)

• I : current intensity, also known as amperage (A)

As you can see, the current intensity, also known as amperage (I) and the resistance (R) are directly proportional to the potential difference, also known as voltage (V). This means that if either the amperage or the resistance increases, the voltage also increases.

For a given voltage, the resistance and the amperage are inversely proportional. For example, if the resistance increases, the amperage must decrease to maintain the same voltage.
