📚 Part 1: Reading & Comprehension

An electric circuit is a path that allows electric current to flow. A simple circuit includes a battery (which supplies energy), wires (which carry the current), a load such as a light bulb (which uses the energy), and a switch (which opens or closes the path). When the switch is closed, the circuit is complete and electrons move through the wires to light the bulb. If a wire is made of metal like copper, it is a good conductor and lets electricity flow easily. Materials like plastic or rubber are insulators and block the flow of electricity. Circuits can be wired in a series (one path) or in parallel (multiple paths). In a series circuit, parts share one path so if one part fails, the whole circuit stops. In a parallel circuit, each part has its own path so other parts can keep working if one fails.
