**Ohm’s Law is a fundamental principle of electricity that relates the electric current flowing through a conductor to the voltage applied across it and the resistance of the conductor.**

It states that:

*The current flowing through a conductor is directly proportional to the voltage applied across it, provided the temperature and other physical conditions remain constant.*

In other words, if you increase the voltage across a conductor, the current flowing through it will also increase, as long as the resistance of the conductor remains constant. Mathematically, Ohm’s Law can be expressed as:

**I = V/R**

Where I is the current flowing through the conductor in amperes (A), V is the voltage applied across the conductor in volts (V), and R is the resistance of the conductor in ohms (Ω).

This relationship between voltage, current, and resistance is important in understanding how electrical circuits and devices work, and it forms the basis for many calculations in electrical engineering and physics.

** Ohm’s Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage, current, and resistance in an electrical circuit**. It 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 between them.

Mathematically, Ohm’s Law is represented by the equation:

V = IR

Where V is the voltage or potential difference between two points in volts (V), I is the current flowing through the conductor in amperes (A), and R is the resistance of the conductor in ohms (Ω).

An **example of Ohm’s Law in action is a simple circuit consisting of a battery, a resistor, and a voltmeter connected in series. If the voltage across the battery is 12 volts and the resistance of the resistor is 4 ohms**, then according to Ohm’s Law, the current flowing through the circuit would be:

**I = V/R = 12V / 4Ω = 3A**

This means that a **current of 3 amperes would flow through the circuit**.

**If the resistance of the resistor were to increase, the current would decrease proportionally, while if the voltage were to increase, the current would increase proportionally, as long as the resistance remains constant. **

Ohm’s Law is a foundational principle in the design and analysis of electrical circuits and is widely used in the field of electrical engineering.
