What is Ohm’s law? | ओम का नियम क्या है ?
Ohm’s law is an important law of physics. The formula for Ohms law establishes the relationship between voltage, current and resistance.
According to Ohms law, the voltage across a conductor in a closed circuit is proportional to the current flowing through it. This is called Ohm’s law.
In other language, if there is no change in the physical state of a conductor like area, length, thickness, temperature etc., then the voltage across the ends of the conductor is proportional to the current flowing in that conductor.
Ohms law formula | ओम के नियम का सूत्र
According to Ohm’s law
Voltage ∝ Current V ∝ I V = IR or I = V/R
Where
V = Voltage, Unit : Volt (v)
I = Current, Unit : Ampere (A)
R = Resistance, Unit : Ohm (Ω)
What is Electric Current (विद्युत धारा)?
The flow of charge (electrons) in a conductor in a closed circuit is called current. The SI unit of current is Ampere (A).
What is resistance (प्रतिरोध)?
It is the property of a conductor that causes obstruction or resistance to the flow of current. The SI unit of resistance is Ohm (Ω).
What is voltage?
The electrical force of current flowing in a conductor is called potential difference or voltage. The SI unit of potential difference is Volt (v).
Example of ohms law (ओम के नियम का उदाहरण)
Question 1: If I = 4A and R = 8Ω, calculate the voltage?
Answer:
According to Ohm’s law
V = IR V = 4 x 8 V = 32V
Question 2: If V = 20 V and R = 4Ω, then calculate the current?
Answer:
According to Ohm’s law
I = V/R I = 20/4 I = 5A
