Question

state ohm law also define resistance​

Answer 1

Answer:

ohm's law states that the current flowing in a conductor is directly proportional to the potential difference across its ends given that the physical conditions such as temperature and shape of the body remains constant

resistance is the obstruction offered to the flow of current by a conductor

Answer 2

Answer:

Ohm's law may be expressed mathematically as V/I = R. That the resistance, or the ratio of voltage to current, for all or part of an electric circuit at a fixed temperature is generally constant had been established by 1827 as a result of the investigations of the German physicist Georg Simon Ohm

Explanation:

What is resistance in Ohm's law?

• Resistance is a measure of the opposition to current flow in an electrical circuit. ... Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance. He is credited for formulating Ohm's Law. All materials resist current flow to some degree.

• Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
