Ohm's Law is a fundamental principle in electric circuits that relates voltage, current, and resistance. It states that the current flowing through a conductor is directly proportional to the voltage across the conductor and inversely proportional to its resistance. This law can be summarized by the equation V = IR, where V represents voltage in volts, I represents current in amperes, and R represents resistance in ohms.

To understand Ohm's Law, let's consider an example. Suppose we have a circuit with a resistor of resistance 10 ohms and a voltage of 20 volts. Using Ohm's Law, we can calculate the current flowing through the resistor by dividing the voltage by the resistance. So, I = 20V / 10Ω = 2A. Thus, the current flowing through the resistor is 2 amperes.

Ohm's Law provides a basic tool for analyzing and predicting the behavior of electric circuits. By manipulating the equation V = IR, we can solve for any of the three variables in a given circuit, as long as we know the values of the other two.

It is important to note that Ohm's Law is only applicable to materials that obey Ohm's Law, known as Ohmic conductors. Non-Ohmic conductors, such as diodes or transistors, do not follow this relationship.
