What is the name of the law that states that the current flowing through a conductor is directly

proportional to the potential difference across it, provided the temperature and other physical conditions

The correct answer is (c) Ohm's law

Ohm's law states that the current flowing through a conductor is directly proportional to the potential difference (voltage) across it, provided the temperature and other physical conditions remain constant. Mathematically, it is expressed as:

​$$I=\frac{V}{R}$$​​

I is the current,

V is the voltage (potential difference),

R is the resistance of the conductor.

Ohm's law is fundamental in understanding electrical circuits and forms the basis for many electrical calculations.

Information Booster:

• Ohm's law is named after the German physicist Georg Simon Ohm, who first formulated the relationship in the 1820s.
• The law holds true for materials that obey linear resistance, meaning that the resistance does not change with varying voltage or current.
• Ohm's law is a key principle in both direct current (DC) and alternating current (AC) circuits, though in AC circuits, the relationship can be more complex due to factors like inductance and capacitance.
• Resistance is a measure of how much a material opposes the flow of electric current and is influenced by factors such as the material's temperature, length, and cross-sectional area.
• In practical applications, Ohm's law is used to calculate the necessary components (like resistors) for designing electrical circuits to ensure they function as intended.

• Kirchhoff's law: Kirchhoff’s laws, which include Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL), are also essential in electrical circuit analysis. However, they deal with the conservation of current and energy, not the relationship between voltage and current in a conductor.
