Transcribed Image Text:The computing task is to write a PYTHON program to read in data from the supplied file for voltage ( V (t)) and current ( I (t)) and plot, via pyplot, the log power, being,
p(t) = log (V (t) I (t))
where log is natural log to base e.
Your program should:
• Prompt for the filename to be read.
• Read in the required data from sample.txt file and display p (t) over the supplied range of t with suitable titles and axis labels.
• You must use a function of the form Logpower(voltage, current) to form the p (t), and a main() program.
