Capacitor Experiments 电容器实验
The following experiments are designed to help students understand the role of a capacitor in a circuit. Using these simple experiments students can discover first hand what capacitors do and how they are different from other components such as batteries.
以下实验旨在帮助学生理解电容器在电路中的作用。通过这些简单的实验，学生们可以直接发现电容器的作用，以及它们与其他组件（如电池）的区别。
Basic Capacitor Discharge Circuit Experiment 基本电容放电电路实验
In this project students can quickly conduct an experiment which demonstrates the function of a capacitor and how it is different from other electrical components such as a battery. The experiment is easy to conduct, just connect a battery to the circuit for a few seconds, then disconnect it. With the battery disconnects you can then push and hold the push switch to see how long the LED light remains lit. Have your students make observations and record their results. Then they can find the minimums, maximum, and average for their results and compare their findings with other groups.
在此项目中，学生可以快速进行一个简单的实验来演示电容器的功能以及它与其他电气部件（如电池）的不同之处。这个实验很容易，只需将电池连接到电路上几秒钟，然后将其断开。在电池断开的情况下，可以按住按钮开关，查看LED灯保持点亮的时间。让学生进行观察并记录结果，找出最小值、最大值和平均值，并将他们的结果与其他组进行比较。
Advanced Capacitor Discharge Circuit Experiment 高级电容放电电路实验
With this experiments students can switch between two different sizes of capacitors using a 3-way switch (SPDT). Then using the push switch students can observe how long the LED light remains lit as the capacitor discharges.
通过这个实验，学生可以使用三路开关（SPDT）在两个不同尺寸的电容器之间切换。然后使用按钮开关，学生可以观察电容器放电时LED灯保持点亮的时间。
Capacitance and Resistance Experiment 电容电阻实验
With the capacitance and resistance experiment students can take their experiments one step further by making predictions and observations about how changes in resistance affects the discharge of a capacitor. With this experiment students not only learn about advanced aspects of electrical engineering and circuit design, they also learn about dependant and independent variables.
通过电容和电阻实验，学生们可以通过预测和观察电阻的变化如何影响电容器的放电来进一步进行实验。通过这个实验，学生们不仅学习了高阶的电子工程和电路设计，还了解了因变量和自变量。
