CTE Resource Center - Verso

Virginia’s CTE Resource Center

Measure energy output of a renewable energy source using proper instruments.

Definition

Measurement should include use of a multimeter to determine energy output of sources such as
  • photovoltaic array
  • wind turbine
  • fuel cell.

Process/Skill Questions

  • What is the most energy efficient renewable energy source? Why?
  • How has the efficiency of renewable energy sources changed over time?
  • How is it possible to determine the electrical load of a device to be powered?
  • Why is the output of a device variable?
  • How are voltage, current, and resistance measured with a multimeter?
  • What measurements can determine the efficiency or level of performance of a fuel cell, a photovoltaic array, or a wind turbine?
  • What variables should be controlled when making measurements on energy transforming systems?
