Question

What is ohm's law.................?​

Answer 1

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.

Answer 2

Answer:

OHM’s Law

OHM’s law states that under no same temperature, electric current flowing through an ideal conductor is directly proportional to the potential difference across its ends.

V ∝ I

V = IR, R – Resistance.

• Resistance is a property of conductor to resist flow of charge through it. Its SI unit is Ohm (Ω).

R = V/I, 1 Ohm = 1 Volt/ 1 Ampere

• I = V/R denotes that Current is inversely proportional to Resistance. Hence, greater the resistance lesser will be the flow of current and vice-versa.
• A rheostat or a variable resistor is a device or a component which allows changing of resistance in a circuit keeping the voltage same.
• In a conductor, electrons are attracted by the atoms. This is a resistive force which is lower for a good conductor but very high for an insulator. A conductor having some resistance is called a Resistor.
