Circuit diagram: [ capacitor/.style= thick, draw, fill=white, rectangle, minimum width=0.8cm, minimum height=1.2cm, label=[font=]above:C , battery/.style= thick, draw, fill=white, rectangle, minimum width=0.8cm, minimum height=1.2cm, label=[font=]above:V , wire/.style=thick, draw, dot/.style=fill,circle,inner sep=1.5pt ] % Battery (0,0) to[battery, l_=9 V] (0,2); (0,2) -- (1,2); (0,0) -- (1,0); % Capacitor plates (2,2) -- (2,0); % Left plate (2.2,2) -- (2.2,0); % Right plate at (2.1, 1) [label=[font=]right:Air/Cardboard Dielectric] ; % Wires connecting battery to capacitor (1,2) -- (2,2); (1,0) -- (2.2,0); % Labels for terminals at (0.5, 2.2) +; at (0.5, -0.2) -; This diagram shows the capacitor being charged by the 9V battery. The two parallel lines represent the aluminum foil plates, separated by the cardboard dielectric. Observations / Measurements: When the battery is connected to the aluminum foil plates, no immediate visible change occurs. After 5 minutes of charging, when the battery is disconnected and a small bulb is connected across the plates, the bulb flashes brightly for a brief moment* and then goes out. If a multimeter is connected across the plates immediately after disconnecting the battery, it will show a voltage reading close to 9 V*. After the bulb flashes, if the multimeter is reconnected, it will show a voltage reading close to 0 V*. Inference / Conclusion: This experiment demonstrates that a simple capacitor can be constructed using aluminum foil as conductors and cardboard as a dielectric. The capacitor stores electrical energy when connected to a battery (charging) and releases this stored energy when connected to a load like a bulb (discharging), causing the bulb to flash. The voltage across the capacitor drops to zero after discharge, confirming the release of stored charge. Precaution(s): Ensure the aluminum foil on one cardboard sheet does not touch* the foil on the other sheet to prevent a short circuit. Maintain a consistent and small separation (approximately 2 mm) between the foil surfaces to ensure effective capacitance. Avoid touching the aluminum foil surfaces directly with bare hands after charging, as this could cause an accidental discharge through the body or introduce unwanted resistance/leakage. Ensure good electrical contact between the connecting wires and the aluminum foil. Use a low-power bulb to clearly observe the brief flash during discharge. Drop the next question. 📸
