Analyze and visualize the given electrical discharge data for a capacitor, focusing on understanding the relationships between time, voltage, and discharge behavior. The dataset consists of measurements of voltage across a capacitor over time during discharge, with specific time intervals and corresponding voltage readings. Your task involves creating two types of plots: a standard linear plot and a semi-logarithmic plot to better interpret the exponential decay characteristic of capacitor discharge. Proper graphing principles should be applied, including labeling axes, adding legends, and using clear markers and lines to improve readability and interpretation.

Capacitor discharge behavior is a fundamental concept in electronics and circuit analysis, typically described by an exponential decay function. When a capacitor discharges through a resistor, the voltage across the capacitor decreases exponentially over time, following the equation:

V(t) = V0 * e^(-t/RC)

where V0 is the initial voltage, R is the resistance, C is the capacitance, and t is the time elapsed.

Given the data, which records voltage at various discrete time intervals during the capacitor's discharge, plotting this data helps visualize the exponential decay process. Creating two types of plots—one with standard linear axes and one with a logarithmic scale on the y-axis—allows for a comprehensive analysis. The linear plot provides an intuitive view of voltage diminishing over time, while the semi-log plot linearizes the exponential decay, making it easier to determine parameters such as the time constant and initial voltage.

In the first plot, the voltage (V) is on the y-axis against time (secs) on the x-axis. This plot should use markers connected by lines, have clearly labeled axes, and include a legend indicating the data series. Proper scaling ensures the data is easily interpretable, revealing the overall decay trend visually.

The second plot involves plotting voltage on a logarithmic scale (log scale) against time. This transformation linearizes the exponential decay, providing a straight line if the data perfectly follows the ideal model. The slope of this line corresponds to the negative reciprocal of the time constant, and the intercept corresponds to the initial voltage. Proper labeling of axes and legends enhances the clarity of this plot. When interpreting this graph, the linear trend can be used to estimate the parameters of the decay model, which can then be compared to theoretical expectations or used for further calculations.

Furthermore, it's important to include a descriptive caption and units for each axis to improve the interpretability of the graphs. Using a consistent color scheme and marker style enhances visual clarity. In practical applications, analyzing these plots can help in estimating component values, diagnosing circuit issues, or designing circuits with specific discharge characteristics.
