## Who was Ohm ?

Before we understand Ohm’s Law (Ohm’s law) we briefly get to know some of Om’s life.

Ohm was born on 16 March 1789 in Erlangen, Germany. He was from a very poor family. Despite his parents being very poor and uneducated, he gave good education to Om and his siblings so that he could not live like them.

Om preferred to do what he had practiced from his childhood, more than he practiced. Om had a dream to become a professor. But his dream came true two years before his death.

He did his higher education from Erlangen University. He gave Ohm’s Law (Om’s law) to the world. Which is named after him. In today’s time, people take measures to reduce power consumption.

Use such devices, which can reduce power consumption. All those equipment and big companies operate only on the important Ohm’s Law given by Ohm.

He found in his Practical that there is a special relationship between Voltage, Current and Resistance. And gave the world the principle of Ohm.

Resistance was discovered by Ohm. The conductor whose resistance will be the lowest. He will be the best conductor, this has been possible only with the principle of Ohm. In 1827, Om’s theory about Resistance was first published in the journal “The Galvanic Current Investigated Mathematically”. It was a great achievement for him.

His doctrine was recognized in 1841 by the Royal Society of London. He was awarded the Kople Medal.

Simon Ohm set up an association between Resistance, Electro Motive Fore and Electric Current. And gave it to the world as a principle. But this theory did not get much recognition. Because Physics was not mathematically recognized in Germany at that time.

In 1852, Ohm received the title of Professor. He died in 1854, 2 years after this. Today we read Ohm’s law V = I × R. Which is a priceless gift given to Ohm’s world.

## Ohm’s Law

When the physical states of the conductor of any complete circuit such as length, area, volume, and temperature are maintained, the electric current of that circuit is proportional to the voltage. And there is an inverse ratio of resistance.

### Ohm’s 3 Important Formulas

**Electric current I = V / R****Conflict R = V / I****Electrical pressure V = I × R**

Here, I = electric current that occurs in Ampere.

V = electric pressure which is in Volt.

R = Resistance that occurs in Ohm.

## Remember Ohm’s formula in this way

The triangle shape given below will be very useful for you to remember the formula from Omh.

**Relationship Between Voltage, Current and Resistance **

There is a special relationship between Voltage, Current and Resistance in any electric circuit like Ohm’s. If the ‘V’ voltage of a circuit of ‘R’ ohm resistance continues to increase, the electric current ‘I’ flowing in that circuit also increases along with them.

Meaning ‘R’ is the same in the circuit

Low Voltage leads to low current flow. And

Higher voltage leads to greater current flow.

If we reverse it, that means the voltage is kept the same and the load resistance ‘R’ is changed, then the current of that circuit will change.

There is more resistance in current flow when the resistance is high. As a result, there is a small amount of current flow in the circuit.

When the resistance decreases, there is less resistance in the flow of current. This causes more current to flow in the circuit.
