Which of the following laws states that- the electric current flowing...
- In 1827, a German physicist Georg Simon Ohm (1787–1854) found out the relationship between the current I, flowing in a metallic wire and the potential difference across its terminals.
- He stated that the electric current flowing through a metallic wire is directly proportional to the potential difference V, across its ends provided its temperature remains the same. This is called Ohm’s law.

Ohm's Law states that the electric current flowing through a metallic wire is directly proportional to the potential difference V, across its ends, provided its temperature remains the same.
Explanation:
Ohm's Law is one of the fundamental laws in electrical circuits and is named after the German physicist Georg Simon Ohm, who first formulated it. It establishes a relationship between current, voltage, and resistance in a conductor.
The law can be mathematically expressed as:
V = I * R
Where:
V is the potential difference (voltage) across the ends of a wire or conductor.
I is the electric current flowing through the wire.
R is the resistance of the wire.
According to Ohm's Law, the current flowing through a metallic wire is directly proportional to the potential difference across its ends. This means that if the voltage increases, the current will also increase proportionally. Similarly, if the voltage decreases, the current will decrease proportionally, as long as the temperature of the wire remains constant.
This law holds true for metallic conductors under normal operating conditions. It implies that the ratio of voltage to current (V/I) is constant for a given conductor, which is known as the resistance (R). Resistance is a measure of how strongly a conductor opposes the flow of electric current.
Ohm's Law is widely used in electrical engineering and plays a crucial role in the design and analysis of electrical circuits. It helps in determining the appropriate wire size, calculating power consumption, and understanding the behavior of various electrical components.
In summary, Ohm's Law states that the electric current flowing through a metallic wire is directly proportional to the potential difference across its ends, provided the temperature remains constant. This law forms the basis for understanding and analyzing electrical circuits.
