Resistors in Series

Definition

Resistors in series are two or more resistors connected end-to-end, so that the same current flows through each resistor. The total resistance of resistors in series is equal to the sum of their individual resistances.

Analogy

Think of resistors in series like people holding hands and forming a human chain. Each person represents a resistor, and they all hold hands to create a continuous path for current flow. Just as it's harder for a group of people to move together compared to an individual, the total resistance increases when resistors are connected in series.

Equivalent Resistance: Equivalent resistance is the single resistance value that can replace multiple resistors connected in series without changing the overall behavior of the circuit.

Voltage Divider Rule: The voltage divider rule states that the voltage across each resistor in a series circuit is proportional to its resistance value.

Kirchhoff's Laws: Kirchhoff's Laws are fundamental principles used to analyze electrical circuits. They include Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL), which help determine voltages and currents at different points within a circuit.
