In 1828, Georg Simon Ohm, a German physicist **electric current and potential difference**”.

Which we call Ohm’s law. Ohm’s law is a formula used to calculate the relationship between voltage and resistance in an electrical circuit.

This rule is so prevalent. compared to **einstein** Of** E=MC^2** is done from.

## Ohm’s law क्या है (what is omh law in hindi )

**Ohm’s law **Definition of** “If the physical state of a substance, such as temperature, does not change, then applied at both its ends.The potential difference (v) is proportional to the carrying current (I) in it. ,**

Meaning, * V∝ I*(Note: After removing this, we use the constant. So that the balance of the equation is maintained)

Now, * V=I×R* ,

### The formula for Ohm’s law,

**V=I×R, **We call it the ohm’s formula.

Note: V = Voltage,

I = Current, in ampere,

R = Resistance,

**Ohm’s law** If you know the value of any two variables, you can easily calculate the third one.

When you want to know the voltage(V),** V = IR**use .

When you want to find the current (I),**I=V/R**use .

When you want to find the Resistance (R),**R=V/I**use .

Note :

(1) Ohm’s law applies only when the physical states are constant.

(2) Ohm’s law **semiconductor** But does not apply.

## Question related to Ohm’s law,

1) If a current of 8A is passing through an electric circuit. And the resistance of the circuit is 16Ω. then calculate the voltage

**Note: The voltage value is to be calculated.**

So V=I×R,

V=8×16, =>128volts

2) If a current of 2A is passing in an electric circuit. And the voltage in the circuit is 14V. Then calculate the resistance.

**Note: The resistance value has to be determined.**

So R=V/I,

R=14/2, =>7Ω

3) If any electric circuit is connected to 10V voltage. And the resistance of the circuit is 5Ω. Then calculate the current i,

**Note: To get the current value,**

So I=V/R,

I=10/5, => 2A
