Challenge: Explore Voltage and Current Relationship
In engineering analysis, understanding the relationship between two variables—such as voltage and current in a circuit—is a key application of correlation analysis and scatter plotting. Correlation quantifies the degree to which changes in one variable are associated with changes in another. A scatter plot visually displays this relationship, allowing you to quickly assess whether the variables move together in a predictable way. In this challenge, you will explore the relationship between voltage and current using real-world engineering data.

You are given two lists: voltage_data and current_data, which represent voltage and current measurements from a circuit. Your task is to:
- Calculate the correlation coefficient between
voltage_dataandcurrent_data. - Create a scatter plot of
voltage_data(x-axis) versuscurrent_data(y-axis). - Return both the correlation coefficient and a string describing the relationship as "strong", "weak", or "negligible" based on the absolute value of the correlation coefficient.
Steps:
- Compute the correlation coefficient between
voltage_dataandcurrent_data. - Plot the data using a scatter plot with appropriate axis labels and a title.
- Determine if the relationship is "strong" (absolute correlation > 0.7), "weak" (absolute correlation > 0.3), or "negligible" (absolute correlation ≤ 0.3).
- Return the correlation coefficient and the relationship description as a tuple.
