Power Demand

Rate this resource

This engineering resource, produced by Mathematic in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can you predict future power requirements? Students are required to complete a table by substituting values into a formula and plot a graph. The activity offers good opportunities to consolidate work on geometric progression. The mathematics covered in this activity is:

  • Be able to write the rule for a sequence in symbolic form
  • Change the subject of a formula
  • Be able to plot data
  • Be able to draw a graph by constructing a table of values
  • Solve problems using the laws of logarithms
  • Solve problems involving exponential growth and decay
