In a series circuit, which component develops the greatest voltage drop?

In a series circuit, the total voltage supplied by the source is divided among the components based on their resistances. According to Ohm's Law (V = IR), the voltage drop across a component is directly proportional to its resistance, given a constant current flowing through the circuit.

Components in a series circuit experience the same current, so the component with the highest resistance will develop the greatest voltage drop. This is due to the fact that as the resistance increases, so does the voltage drop across that component while the current remains constant throughout the circuit.

In contrast, a component with the lowest resistance would have the smallest voltage drop, while the notion that any component would have an equal drop does not hold true for a series circuit. Additionally, the order in which components are connected does not affect the voltage drops; it is solely determined by their respective resistances. Thus, the component with the highest resistance is responsible for the largest voltage drop in the circuit.
