Students in Teacher Glenn’s EP M5 Science class investigated how capacitors charge and discharge through resistors, and how this process can be measured over time. Creating a circuit with a capacitor, resistor, switch, wires, and voltmeter, students first charged the capacitor and then discharged it while recording voltage readings at timed intervals. By analyzing their results and plotting voltage against time, they observed the characteristic exponential decay curve of a discharging capacitor. The experiment was repeated with different resistance and capacitance values, allowing students to compare how the time constant (RC) affects the shape of the graph. This hands-on lab gave students practical insight into the mathematics and physics of capacitors, bridging theory with real world applications in electronics.
