Georg Ohm's law is a fundamental principle in physics that describes the relationship between electric current, voltage, and resistance in an electrical circuit. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance of the conductor.

This relationship is expressed mathematically as:

I = V/R

where I is the current, V is the voltage, and R is the resistance.

Georg Ohm, a German physicist and mathematician, first formulated this law in 1827 based on his experiments with electrical circuits. His work was groundbreaking because it provided a way to quantitatively measure and predict the behavior of electrical circuits, which is essential for the development of modern electronics.

Ohm's law has many practical applications in fields such as electrical engineering, physics, and electronics. It is used to calculate the amount of current that will flow through a circuit given a certain voltage and resistance, or to determine the resistance needed to achieve a desired current in a circuit. It is also used to design and analyze electrical circuits, and to troubleshoot problems in electrical systems.

In addition to its practical applications, Ohm's law is also an important concept in physics because it helps us understand the nature of electrical charge and the behavior of electrons in a conductor. It is a fundamental law that is often used in conjunction with other laws of physics, such as the law of conservation of energy, to analyze and understand electrical systems and phenomena.

Overall, Georg Ohm's law is a fundamental principle that has had a significant impact on the field of physics and has practical applications in many areas of modern technology. Its importance cannot be overstated, and it continues to be a fundamental concept that is studied and applied in fields related to electricity and electronics.

## Ohm’s Law

Find the voltage between two points. Make an electric circuit by connecting all these components accurately but using only one cell as shown in figure a given below. Even students can easily download the practice question papers of Ohms Law Formula. For example, when we increase the number of cells in a torch, the brightness of the bulb increases. Now, when we find the ratio voltage to current for each case, we will find that it is almost the same. Perhaps you should alter the site to reflect this. The power triangle is used to see the worth of electrical power, voltage, and current once the values of the opposite 2 parameter unit are given to us.

To remember this, the Ohm triangle calculator shown in the figure might be helpful. When we plot the graph between voltage and current for such materials, the graph will be non-linear. Answer: The reciprocal of resistivity is conductivity. He performed a large series of experiments that showed the relation between applied voltage and current through a conductor. Find the voltage between two points. Ohm was a teacher at a gymnasium high school in Cologne at that time, and he decided to resign. Here, the voltage is analogous to water pressure, it is that the quantity of water flowing through the pipe, and therefore the resistance is that the size of the pipe.
