Which law states that the current through a conductor between two points is directly proportional to the voltage across the two points?

Ohm’s Law is a fundamental principle in electrical theory that establishes the relationship between voltage, current, and resistance in a conductor. It states that the current flowing through a conductor is directly proportional to the voltage across it, provided that the temperature and other conditions remain constant.

Mathematically, Ohm’s Law can be expressed as ( I = \frac{V}{R} ), where ( I ) is the current (in amperes), ( V ) is the voltage (in volts), and ( R ) is the resistance (in ohms). This law is very useful in circuit analysis and design, allowing engineers and technicians to predict how much current will flow at a given voltage and resistance.

The other laws mentioned in the question focus on different concepts: Kirchhoff's Law relates to the conservation of charge and energy in electrical circuits; Faraday's Law deals with electromagnetic induction; and Newton's Laws pertain to motion and forces in classical mechanics. These principles do not describe the direct proportionality between current and voltage as Ohm's Law does.
