Consider a string of christmas lights, where each bulb represents an impedance. This series arrangement of impedances ensures a uniform current across each component. Applying Kirchhoff's Voltage Law, the equivalent impedance equals the summation of individual impedances, similar to resistors in series. The source voltage gets distributed proportionally among multiple components based on their respective impedances, adhering to the voltage division principle. In a series connection, the malfunction of a single bulb triggers an open circuit, disrupting the current flow. So, christmas lights are usually wired in a parallel configuration, guaranteeing a steady voltage across each component. Applying Kirchhoff's Current Law to this parallel circuit reveals that the reciprocal of the equivalent impedance equals the sum of the reciprocals of the individual impedances, similar to resistors in parallel. So, the equivalent admittance is given by the sum of the individual admittances. The source current divides among the components in inverse proportion to their impedances, demonstrating the current division principle. Here, each component establishes an independent pathway to the power source, enabling an isolated current flow.
