# CTE Resource Center - Verso - Sustainability and Renewable Technologies Task 1709747299

# 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?

## Mathematics

### A.1

The student will
1. represent verbal quantitative situations algebraically; and
2. evaluate algebraic expressions for given replacement values of the variables.

### A.3

The student will simplify
1. square roots of whole numbers and monomial algebraic expressions;
2. cube roots of integers; and
3. numerical expressions containing square or cube roots.
