Which law relates voltage, current, and resistance?

• A. Faraday's Law
• B. Kirchhoff's Law
• C. Ohm's Law
• D. Newton's Law

Answer: (C)

The law that specifically relates voltage, current, and resistance is Ohm's Law. This principle states that 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. Mathematically, this is expressed as V = IR, where V is the voltage (in volts), I is the current (in amperes), and R is the resistance (in ohms). Understanding Ohm's Law is fundamental in electronics and electrical engineering because it allows for the calculation of one of these variables when the other two are known. This relationship is essential for designing circuits, analyzing electrical systems, and troubleshooting electrical issues. The other options, while significant in their own right, address different aspects of electrical theory. Faraday's Law pertains to electromagnetic induction, Kirchhoff's Law involves the conservation of charge and energy in electrical circuits, and Newton's Law relates to motion and forces, making them unrelated to the direct relationship of voltage, current, and resistance.
