What is a Circuit?

A circuit is a path that current electricity or electrons can flow through. Current electricity is a type of human-made electricity. A simple circuit is made out of four parts: the power source, wires, the load, and a switch

How Does a Simple Circuit Work?

A simple circuit works by electrons, which are negatively charged, exit from the negative terminal of the power source. Then, the electrons flow through the wire to the load. The load is whatever is consuming the electricity. The electrons power the load and come through the switch. If the switch is open, no power flows through. If the switch is closed, the power flows through. Then, the electrons flow from the switch to the positive terminal of the power source. That is a simple circuit!
