What happens to the voltage across each component in a series circuit?

In a series circuit, the voltage across each component divides among the components based on their resistance or impedance. According to Ohm's Law, the voltage across each component in a series circuit is proportional to its resistance. This means that components with higher resistance will drop more voltage, while those with lower resistance will drop less. The total voltage supplied by the source is equal to the sum of the voltage drops across all individual components.

This fundamental behavior allows for the analysis of circuit performance, as you can determine how the total voltage is allocated across each of the components based on their individual properties. Thus, in series circuits, the voltage does not remain constant across all components nor does it increase with each component; rather, it is shared in a way that reflects the resistance values of the components in the circuit.
