What are the primary rules for series circuits?

In a series circuit, the primary rules dictate that the voltage across various components is divided among them while the current remains constant throughout the entire circuit. This means that regardless of how many resistors or other components are present, the same current flows through each one.

The total voltage supplied by the source, such as a battery, is distributed among all components in the circuit, and the sum of the individual voltage drops across those components equals the total voltage. This characteristic affects how components behave and interact in the circuit, leading to practical implications such as needing to calculate total resistance and voltage drops to understand circuit performance effectively.

The behavior of series circuits is pivotal in many applications ranging from basic electrical setups to more complex systems, emphasizing the importance of understanding these rules in practical scenarios.
