Question

explain ohms low ??​

Answer 1

Explanation:

Ohms law

Ohm's law states the relationship between voltage, current and resistance. According to this law, the amount of electricity passing through a conductor between two points in a circuit is directly proportional to the voltage across the two points, for a particular temperature.

Ohm expressed his idea in the form of a simple equation, E = IR, which describes the interrelation of current, voltage, current and resistance.

According to this algebraic expression, the voltage (E) across the two points is equal to current (I) multiplied by resistance (R).

Ohm's Law is a very helpful and simple tool for electric circuit analysis.

Ohm's law was discovered by German physicist Georg Simon Ohm.

Early on, it was believed that Ohm's law would not be unsuccessful at the atomic scale. But later, researchers proved that Ohm's law is applicable for silicon wires with a width of only four atoms and a height of only one atom.

Ohm’s Law ~

When an electric potential difference (V) is applied across a conductor , some current (I) flows through it. The flow of current is opposed by the resistance of the conductor and circuit. The relation between voltage, current and resistance is explained by the ohm’s law.

Ohm’s laws state that the current through any two points of the conductor is directly proportional to the potential difference applied across the conductor, provided physical conditions i.e. temperature, etc. do not change. It is measured in (Ω) ohm.

Additional information~

Limitations of Ohm’s Law:-

☆Ohm’s law is not applicable in unilateral networks. Unilateral networks allow the current to flow in one direction. Such types of network consist elements like a diode, transistor, etc.

☆It is not applicable for the non-linear network. In the nonlinear network, the parameter of the network is varied with the voltage and current. Their parameter likes resistance, inductance, capacitance and frequency, etc., not remain constant with the times. So ohms law is not applicable to the nonlinear network.

☆Ohm’s law are used for finding the resistance of the circuit and also for knowing the voltage and current of the circuit.
