The relationship between current (I), voltage (V), and resistance (R) in a resistor is described by Ohm’s Law: I = V/R. This equation signifies that the current through a resistor is inversely proportional to its resistance. As resistance increases, the current decreases, and vice versa, under constant voltage. Higher resistance restricts the flow of electrons, resulting in a lower current. Conversely, lower resistance facilitates a higher current. Ohm’s Law is fundamental in understanding and predicting the behavior of resistors in electric circuits, providing a quantitative link between current, voltage, and resistance in a linear relationship.
