电路元件为何表现不同
Why circuit components behave differently
比较并解释电路元件工作方式的差异，包括灯泡亮度、蜂鸣器响度和开关位置等。
Compare and give reasons for variations in how circuit components function, including brightness of bulbs, loudness of buzzers, and switch positions
学习证据 / Evidence
- 解释为什么在串联电路中增加更多元件会降低亮度或响度（能量被共享）。
- 比较不同配置的电路并预测元件的行为。
- 对观察到的元件功能差异给出合理的解释。
- Explain why adding more components in series reduces brightness/loudness (energy shared)
- Compare circuits with different configurations and predict component behaviour
- Give reasoned explanations for observed variations in component function
评估问题 / Assessment
如果{{name}}在串联电路中接入第二个灯泡后灯泡变暗，他们能解释能量是如何在两个灯泡之间共享的吗？
If {{name}} adds a second bulb to a series circuit and it gets dimmer, can they explain why the energy is being shared between the two bulbs?
