What is V = IR better known as?

V = IR is an important equation in the world of physics and electrical engineering. It represents Ohm's Law, which relates three fundamental quantities in electric circuits: voltage (V), current (I), and resistance (R).

Ohm's Law, named after the German physicist Georg Simon Ohm, states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. In other words, the equation V = IR describes the relationship between these three variables.

Let's break down the equation:

• V represents voltage, which is the electric potential difference between two points in a circuit. It is measured in volts (V).
• I represents current, which is the flow of electric charge through a conductor. It is measured in amperes (A).
• R represents resistance, which is the opposition to the flow of current in a circuit. It is measured in ohms (Ω).

By rearranging the equation, we can also calculate the individual variables:

• Voltage (V) = Current (I) × Resistance (R)
• Current (I) = Voltage (V) / Resistance (R)
• Resistance (R) = Voltage (V) / Current (I)

Ohm's Law is a fundamental principle in electrical engineering and plays a crucial role in designing and analyzing circuits. It allows engineers to predict and control the behavior of electrical systems by manipulating voltage, current, and resistance.

Understanding V = IR is essential for anyone working with electronics, as it provides the foundation for many concepts and calculations in the field. Whether you are designing a simple circuit or troubleshooting a complex electrical system, Ohm's Law is a powerful tool that enables you to make informed decisions and ensure the safe and efficient operation of electrical devices.
