Answer

Answer

##ohm's law was proposed py a german physict george simon ohm

##according to ohm's law at a constant temparature. a steady current 'I' flowing through the resistor is directly proportional to the potential difference 'V'.

## I~V. -1

## I/V=constant. -2

## let the proportionality constant be 1/R. -3

## substitute. 3 in 2

## I/V=1/R

## by cross multiplying we get,

## IR=V

## by changing side we can get ohm's law formula

## V=IR

I HOPE THAT YOU CAN UNDERSTAND THIS OHM'S LAW EASILY VIRENDRA JHA

Answer

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance. Ohm's law is named for German physicist Georg Ohm (1789-1854). A simple formula, Ohm's law, is used to show the relationship of current, voltage, and resistance.

Answer

Ohm's Law

Ohm's law states the relationship between current, voltage and resistance in an electrical circuit. It was discovered by Georg Simon Ohm, a German physicist in 1827. According to Ohm's law, the current flowing through a conductor is directly proportional to the voltage applied across it, provided the temperature and other physical conditions remain constant.

The Formula for Ohm's Law

Ohm's law is expressed mathematically as follows:

V = I x R

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

The Explanation of Ohm's Law

Ohm's law can be explained using the analogy of water flowing through a pipe. The current is like the flow of water in a pipe, the voltage is like the pressure of water and the resistance is like the diameter of the pipe. Just as the flow of water in a pipe is directly proportional to the pressure applied and inversely proportional to the diameter of the pipe, the flow of current in a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor.

The Proof of Ohm's Law

Ohm's law can be derived from the basic principles of electromagnetism. The flow of current in a conductor is caused by the flow of electrons. When a voltage is applied across a conductor, it creates an electric field that exerts a force on the electrons, causing them to move. The resistance of the conductor is determined by the number of electrons that are available to carry the current. The greater the number of electrons, the lower the resistance of the conductor.

When a voltage is applied across a conductor, the current that flows through it is determined by the number of electrons that are available to carry the current. The greater the number of electrons, the greater the current that will flow. This relationship is expressed mathematically as V = I x R, where V is the voltage, I is the current and R is the resistance of the conductor.

Therefore, Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, provided the temperature and other physical conditions remain constant.
