Ohm’s law definition

Ohm’s law definition class 10 Ohm’s law is the relation between electric current and potential difference Most of the amount of current passing through a conductor is directly proportional to the voltage applied to it. Physiology is an ohms law definition German of science Ohm is the first to use Ohm’s laws.

state ohms law:

V = I R


Explain ohm’s law holds true when the given temperature and other physical factors remain in place. In some cases, the temperature rises as the current increase An example of this is when the filament of a light bulb in which the current violates ohm’s law derivation.

What is ohms law in physics we understand that by doubling and tripling the voltage, the current in the circuit is doubled and tripled? Similarly, when we compare, we come to know one thing doubling the accumulated resistance reduces the current in the circuit state and explains ohms law. 

Ohm’s Law Formula

Voltage= CurrentĂ— Resistance
V= voltage, I= current and  R= resistance
The International System of Units of resistance is ohms and is denoted by Ω
This law is one of the most basic laws of electricity. It helps to calculate the power, efficiency, current, voltage, and resistance of an element of an electrical circuit.

Limitation of Ohm’s law

  • Ohm’s law does not apply to one-way networks On the other hand the network allows the current to flow in one direction. In this type of network, there are elements like a diode, transistor, etc.
  • Ohm’s law does not apply to cable elements either. 
  • Non-linear elements are those to which the applied voltage cannot be proportional.
  • This means that the resistor in those elements changes for different values ​​of voltage and current Elements Example Thyristor.


  1. Initially, the key is turned off and the restart is adjusted to obtain the minimum reading in the ammeter and voltmeter
  2. The current in the circuit is gradually increased by rotating the sliding terminal of the restart. 
  3. The relative value of the potential difference between the current flowing in the circuit and the resistance wire during operation is recorded.


I told you guys in simple language and short the explanation and limitations of Hans Law, hope you guys have liked it very much. If you have any questions in your mind then you can contact me, and I will give you complete information you can also comment below the post state and explain ohms law.
