Go Direct Energy Sensor
Go Direct Energy Sensor
In this session, students will:
- Assemble the 2019 wind turbine created by the Middle School Team for their 2019 challenge.
- Using the Go Direct Energy device, they will learn how it can collect and show on a computer the data their current wind turbine generates in terms of voltage, current, power, resistance, and energy.
- Change variables (number of blades, pitch of blades) to see how the data changes.

Terms:
- voltage: an electromotive force or potential difference expressed in volts. A volt is a single unit of voltage and equal to one joule which is a derived unit of energy.
- current: a flow of electricity which results from the ordered directional movement of electrically charged particles.
- power: energy produced by electricity and used to operate a device.
- resistance: the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.
- energy: is used to work a machine or light a bulb.
