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

Ohm's Law describes the fundamental relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. According to this 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 mathematically expressed as V = I × R.

This law is critically important in circuit analysis and design, as it allows for the calculation of one electrical quantity if the other two are known. Understanding this relationship is essential for predicting how circuits behave under different conditions and helps in troubleshooting and designing electrical systems.

The other choices relate to different concepts in electrical and physical principles. Kirchhoff's Law deals with current and voltage in complex circuits, Faraday's Law focuses on electromagnetic induction, and Newton's Law pertains to the motion of objects rather than electrical relationships.
