This document discusses series and parallel lighting circuits. A series circuit has one power source that runs through components sequentially, while a parallel circuit splits the power source to run through multiple components simultaneously. Parallel circuits allow a single power source to power multiple lights or devices at once.

1. Series & parallel circuit

3. Parallel circuit
One power supply point to parallel of two point or more circuit of DC cable or Ac
cable to generate energy to light up the led lamp.
