What is Ohm's law?

Question

State the Ohm's law and give an example of conductor that obey Ohm's law?

Answer 1

Ohm's law states that the electric current in a given metallic conductor is directly proportional to the potential difference applied between it's ends, provided that the temperature of the conductor and other physical factors such as length and cross-sectional area remain constant.

Conductors that obey Ohm's law are called Ohmic conductors, e.g metals and alloys.

Answer 2

Ohm's Law states that the current passing through a conductor is directly proportional to the voltage applied, provided the temperature remains constant.

Answer 3

states that the current passing through a conductor between two points is directly proportional to the voltage drop across the conductor provided that temperature and other physical conditions are kept constant.In other words,the ratio of the voltage applied to a circuit to the current flowing in the circuit is constant,,and this constant is called the resistance of the circuit...Mathematically,Ohms law can be expressed as V=IR,,where V is voltge drop,I is the current and R is the resistance of the circuit

Answer 4

Ohm's law is a fundamental principle in electrical engineering and physics that describes the relationship between the voltage, current, and resistance in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. In other words, the mathematical expression for Ohm's law is:

V = IR

where V is the voltage, I is the current, and R is the resistance.

This means that if you increase the voltage across a conductor while keeping the resistance constant, the current through the conductor will increase proportionally. Conversely, if you increase the resistance while keeping the voltage constant, the current will decrease proportionally. Ohm's law is commonly used to calculate the current flowing through a circuit, given the voltage and resistance, or to calculate the resistance of a component given the voltage and current.
