Which law states that voltage equals current times resistance?

The law that states that voltage equals current times resistance is known as Ohm's Law. This fundamental principle in electrical engineering establishes the relationship between voltage (measured in volts), current (measured in amps), and resistance (measured in ohms). The mathematical expression of Ohm's Law is V = I × R, where V represents voltage, I represents current, and R represents resistance.

Understanding this relationship is crucial for analyzing electrical circuits, as it allows you to calculate one of the three variables if the other two are known. For example, if you know the current flowing through a resistor and its resistance, you can determine the voltage across that resistor.

Other laws mentioned, such as Kirchhoff's Law, deals with the conservation of charge and energy in electrical circuits, while Faraday's Law pertains to electromagnetic induction and the relationship between electric current and magnetic fields. Newton's Law relates to motion and does not apply to electrical circuits. Therefore, Ohm's Law is the correct answer as it specifically defines the relationship between voltage, current, and resistance in electrical applications.
