What is Ohms law and definition of ohms law?¿​

Answer 1

Answer :-

Ohm's law states that the potential difference between the two ends of a conductor is directly proportional to the strength of current of the conductor.

V ∝ I

=> V = IR

(where V = potential difference,

I = current strength & R = resistance)

• The property by virtue it blocks the passage of electric current is called resistance. It's SI unit is ohm.

• The opposite of resistance is conductance. It's SI unit is mho.

• Potential difference is said to be the difference in potential between the two ends of conductor. It's SI unit is volt.

• The number of electrons which flow through unit cross-sectional area of conductor within a second is called current strength. It's SI unit is Ampere.

Answer 2

$\bf\huge{\pink{Ohm's \:law }}$

Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.

Theory

Ohm's law states that the current I in a resistor is proportional to the potential difference V across it, provided that the temperature of the object is constant. In. equation form, it says. where the proportionality constant R is the resistance of the device .

The main applications of Ohm's law are: To determine the voltage, resistance or current of an electric circuit. Ohm's law is used to maintain the desired voltage drop across the electronic components. Ohm's law is also used in DC ammeter and other DC shunts to divert the current.

Ohm’s Law Equation: V = IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.
