In this learning activity you'll explore how to reduce electromagnetic interference (EMI) and crosstalk between adjacent wires.
Learners examine how a radiation pyrometer converts the frequency of electromagnetic waves to a temperature reading.
Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.
Learners consider the most common types of electromagnetic waves and the kinds of hardware used in a wireless network. A short quiz completes the activity.
