What law describes the relationship between voltage, current, and resistance?

Ohm's Law is the principle that defines the relationship between voltage, current, and resistance in an electrical circuit. According to Ohm's Law, the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. Mathematically, this is expressed as V = I × R.

This law is fundamental in understanding how electrical circuits operate. It allows for calculations involving the amount of current that will flow in response to a given voltage and resistance, making it essential for designing and analyzing electrical circuits.

In contrast, Kirchhoff's Laws deal with the principles of conservation of charge and energy in circuit networks, while Newton's Laws govern the motion of objects and are not applicable to electrical concepts. Faraday's Law relates to electromagnetic induction and the generation of electric current through changing magnetic fields, which is a different aspect of electricity. Thus, Ohm's Law is specifically the law that directly addresses the relationship among voltage, current, and resistance.
