Resistors in Series. Resistors are said to be in series whenever the current flows through the resistors sequentially. Consider Figure \(\PageIndex{2}\), which shows three resistors in series with an applied voltage equal to \(V_{ab}\). Since there is only one path for the charges to flow through, the current is the same through each resistor.

Resistors are devices that obstruct the flow of electric current in the circuit. They provide the hindrance to the path of the current which flows in the circuit.. A resistor is a two-terminal electrical component that works by reducing the flow of charge and voltage levels in the circuit. Most of the circuits have one or more resistors to oppose the flow of current and balance the circuit.
