Doubt in plotting graph between small and large values

Click For Summary
SUMMARY

This discussion focuses on plotting voltage versus current graphs for the IN4001 silicon diode to determine dynamic resistance under both forward and reverse bias conditions. The relevant equation for calculating dynamic resistance is ∆R = ∆V/∆I. Participants debated whether to plot both data sets on a single graph or separately, concluding that the task requires a single graph with appropriate scaling for both data sets. The discussion also referenced the datasheet for the IN4001 diode for additional context.

PREREQUISITES
  • Understanding of diode characteristics, specifically the IN4001 silicon diode
  • Knowledge of graphing techniques for voltage and current data
  • Familiarity with the concept of dynamic resistance and its calculation
  • Ability to interpret data from electronic component datasheets
NEXT STEPS
  • Learn how to plot voltage-current characteristics for diodes using software like MATLAB or Python's Matplotlib
  • Study the datasheet for the IN4001 diode to understand its electrical characteristics
  • Explore techniques for scaling graphs to accommodate disparate data ranges
  • Investigate the implications of dynamic resistance in circuit design and analysis
USEFUL FOR

Electrical engineering students, electronics hobbyists, and professionals involved in semiconductor device analysis and circuit design will benefit from this discussion.

Your attachments are not working. Do they show your work toward the solutions?

Are you asking how to plot both sets of data in one graph? I don't think you are being asked to do that. They’re two separate graphs.

thank you sir for taking time to respond to my doubt. but sir it is asked to plot both the data's in a single graph. in that case what scale will be suitable to plot the data's. both the data's given are for same silicon diode IN4001

It shows the data's for plotting the graph sir

is it now working sir?

Not the way I read it: (draw the graph between the voltage and the current and hence find the dynamic resistance of the diode) for both forward and reverse bias condition.
