Ohm's Law describes the relationship between current, voltage, and resistance in a circuit, represented by the equation V = IR. By manipulating voltage, current, and resistance, one can understand how they affect each other in a circuit. Using Ohm's Law, you can calculate voltage drops across resistors in circuits.
Ohm's Law 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. Mathematically, it is represented as V = IR, where V is voltage, I is current, and R is resistance.
When applying Ohm's Law in a circuit, if you increase the voltage while keeping the resistance constant, the current will increase. Conversely, if you increase the resistance while keeping the voltage constant, the current will decrease. This relationship is fundamental in understanding how current, voltage, and resistance interact in circuits.
Ohm's Law can be illustrated through various circuit diagrams, such as circuits with resistors in series and parallel. By using Ohm's Law, you can calculate parameters like voltage drops across resistors based on the current flowing through them.
