Introduction to Electric Circuits

The video tutorial explains electric circuits, which are complete closed paths for electric charges to flow. It covers the components of a circuit, including the energy source, load (resistance), and switch. The tutorial also distinguishes between open and closed circuits, explaining that a closed switch allows current to flow, lighting the bulb, while an open switch stops the flow.
