Draw the diagrams of the circuits you designed.
The circuit diagram should include: (1) A 9V DC battery as the power source, (2) A switch to control the circuit, (3) A 220 ohm resistor connected in series to limit current, (4) An LED with the longer leg (anode) connected toward the positive terminal and shorter leg (cathode) toward the negative terminal. For the buzzer circuit, replace the LED with a buzzer while keeping the same resistor and battery configuration. The components should be connected in a closed loop for current to flow.
Explanation
The chapter provides basic circuit symbols including battery, resistance, switch, diode, and LED. Students should use these standard symbols to draw their circuit diagrams. The circuit follows a series configuration where all components are connected end-to-end in a single path.
