According to Ohm's Law, how is current (I) related to voltage (E) and resistance (R)?

Ohm's Law describes the relationship between current (I), voltage (E), and resistance (R) in an electrical circuit. According to the law, the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. This can be expressed mathematically as:

I = E / R

Here, if the voltage (E) increases while the resistance (R) remains constant, the current (I) will also increase, demonstrating direct proportionality. Conversely, if the resistance (R) increases while the voltage (E) remains constant, the current (I) decreases, illustrating the inverse relationship.

This understanding of current being both directly related to voltage and inversely related to resistance is fundamental in electrical engineering and is crucial for anyone studying or working in the field. In this case, selecting the option that states current is directly proportional to voltage and inversely proportional to resistance accurately reflects the principle outlined by Ohm’s Law.
