Define Ohm's law?

Question

Define Ohm's law?

Answer

At constant temperature , V = IR.

Answer

Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR. This relationship between current, voltage, and relationship was discovered by German scientist Georg Simon Ohm. Let us learn more about Ohms Law, Resistance, and its application.

Answer

Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.

To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists.

E = I x R

When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.

Named for German physicist Georg Ohm (1789-1854), Ohm's Law addresses the key quantities at work in circuits:

Answer

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Answer

Ohm's Law:

Ohm's law 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.

Explanation:
Ohm's law is named after the German physicist Georg Simon Ohm, who discovered this relationship between current, voltage, and resistance in 1827. It is one of the fundamental principles in electrical circuit analysis and is applicable to a wide range of electrical components and systems.

The Formula:
Ohm's law is mathematically represented by the equation:
V = I * R
where:
- V represents the voltage measured across the two points in volts (V)
- I represents the current flowing through the conductor in amperes (A)
- R represents the resistance of the conductor in ohms (Ω)

Direct Proportionality:
According to Ohm's law, the current flowing through a conductor is directly proportional to the voltage across it. This means that if the voltage increases, the current flowing through the conductor also increases, and vice versa. The relationship is linear as long as the resistance remains constant.

Inverse Proportionality:
Ohm's law also states that the current flowing through a conductor is inversely proportional to its resistance. This means that if the resistance increases, the current decreases, and if the resistance decreases, the current increases, as long as the voltage remains constant.

Example:
Let's consider a simple circuit consisting of a resistor connected to a battery. If we increase the voltage across the circuit, the current flowing through the resistor will also increase, assuming the resistance remains constant. Similarly, if we increase the resistance, the current will decrease, assuming the voltage remains constant.

Applications:
Ohm's law is widely used in electrical engineering and plays a crucial role in the design and analysis of electrical circuits. It helps determine the appropriate values of resistors, capacitors, and other components needed to achieve desired currents and voltages in a circuit. Ohm's law is also used in various practical applications, including power distribution, electronics, and telecommunications.

Conclusion:
Ohm's law provides a fundamental relationship between current, voltage, and resistance in an electrical circuit. It is a powerful tool that helps engineers and scientists understand and analyze the behavior of electrical systems. By applying Ohm's law, they can calculate and control the flow of current in various circuits, enabling the development of efficient and reliable electrical devices and systems.
