What is common to all components of a series circuit?

In a series circuit, one of the primary characteristics is that the same current flows through all components. This is due to the nature of a series arrangement where all components are connected end-to-end, forming a single path for the flow of electric charge.

When electricity flows through a series circuit, the current has only one route to follow, meaning that every component in that circuit experiences the same amount of current. This consistency in current leads to predictable behavior in the circuit and is fundamental to the operation of series circuits.

While voltage can be different across various components (since the total voltage is divided among them), and power and resistance are affected by the amount of current present, it is the current that remains uniform throughout. Understanding this principle is crucial in both practical applications and theoretical analysis of electrical circuits.
