"Build a parallel resistor circuit with a 5V battery and two 1k resistors."
"Create a circuit with an LED and a Zener diode for 5.1V regulation."
"Create a circuit with a 5V battery, a capacitor, and a switch to show the capacitor charging and discharging over time."
"Create a series RLC circuit with a charged capacitor, an inductor, and a resistor to demonstrate damped oscillations and resonance."
"Build a voltage divider with 10V source and two 1k resistors."
"Build a circuit with a 5V battery, three resistors, and four switches to demonstrate series and parallel paths depending on which switches are closed."
"Create a missing pulse detector circuit using a 555 timer in monostable mode. The input should be a 60Hz square wave with 5V peak-to-peak. The circuit should output low if a pulse is missed."
