Which principle directly relates current, voltage, and resistance in an electrical circuit?

The principle that directly relates current, voltage, and resistance in an electrical circuit is Ohm's Law. This fundamental law 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, it is usually expressed as ( V = IR ), where ( V ) is the voltage, ( I ) is the current, and ( R ) is the resistance.

Understanding Ohm's Law is crucial for anyone working with electrical systems, including those engaged in electrofishing practices. It helps in predicting how changes in voltage or resistance will affect the current flowing through a circuit. For example, in electrofishing, accurate control of voltage and current is vital for effective fish capture and ensuring the safety of aquatic life.

In contrast, Watt's Law relates to the power in an electrical circuit and involves the relationship between voltage, current, and power (represented as ( P = VI )). Kirchhoff's Law, specifically Kirchhoff's Voltage and Current Laws, deal with the conservation of charge and energy in electrical circuits but do not specifically describe the relationship between voltage, current, and resistance. Faraday's Law pertains to electromagnetic induction and
