Ohm’s Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, given a constant temperature. In simpler terms, it describes how current (I) behaves in relation to voltage (V) and resistance (R) in an electrical circuit. If you increase the voltage across a conductor (like a wire), the current flowing through it will also increase, provided the resistance remains constant.

Ohm’s Law is applicable to any electrical circuit where there is resistance to the flow of electric current.

It can be observed and applied in various electronic devices, household wiring, industrial equipment, and virtually all electrical systems where current, voltage, and resistance play a role.

The basic formula for Ohm’s Law is expressed as: V=I×RV = I \times RV=I×R, where VVV represents voltage (in volts), III represents current (in amperes), and RRR represents resistance (in ohms).

This formula indicates that the voltage across a resistor is equal to the product of the current flowing through it and the resistance of the resistor.

The SI unit of Ohm’s Law is the ohm, denoted by the symbol Ω.

It represents the measure of electrical resistance within a circuit.

Ohm’s Law provides a fundamental relationship in electrical engineering and physics, guiding the design, analysis, and operation of electronic circuits and systems worldwide.
