In today’s design and technology lesson, students learned about electrical and electronic component symbols and what components are, including input devices like switches and batteries, and output devices such as filament bulbs and LEDs. The lesson emphasized that components must be connected to form a circuit for them to function properly. Students also watched a video demonstration that covered various components, including the cell and battery, which supply electrical energy, and the toggle switch, which allows current to flow in a circuit when in the closed position.
