Current Electricity: How Electrons Power Our World
- Current electricity is the steady flow of electrons through a conductor like a wire.
- It powers almost everything around us—from light bulbs to laptops to trains.
- Voltage is the push that drives electrons, while current is the amount flowing.
- Direct current (DC) flows one way, while alternating current (AC) switches direction rapidly.
- Thomas Edison championed DC, while Nikola Tesla popularized AC for power grids.
- Metals like copper and aluminum are preferred conductors because electrons move easily in them.
- Insulators such as rubber or plastic prevent current from escaping, keeping us safe.
- Circuits provide pathways for electrons—open circuits stop the flow, closed ones allow it.
- Electric current is measured in amperes, showing how many charges pass each second.
- From charging phones to running cities, current electricity is the heartbeat of modern life.
