创建一个交互式工具供学生使用滑块实验电压与电阻。当学生调节这些数值时，一个持续更新的图表实时显示利用 I = V/R 计算出的电流。该工具应用最优范围限制确保有效的学习和可视化。

Make a tool where students input voltage and resistance to graph current.
Allow real-time tweaks to variables for instant graph updates.

Q: Do you prefer using sliders, text inputs, or both for entering the voltage and resistance values?
A: sliders

Q: Should the graph display the calculated current (using I = V/R) as a single data point or as a continuously updating plot?
A: yes

Q: Are there any specific ranges or limits for voltage and resistance that the tool should enforce?
A: optimal
