1. A closed circuit: This means a continuous path for the electric charge to flow. Think of it like a pipe for water – the current can't flow if there are gaps or breaks in the path.
2. A potential difference (voltage): This is what drives the charge. Imagine a hill – the higher the hill, the faster the water flows downhill. Similarly, a higher voltage means a stronger force pushing the charges, resulting in a higher current.
3. A material that conducts electricity: This is a material that allows electric charges to flow easily. Metals are good conductors, while materials like rubber and plastic are insulators.
