# EK 307 – Electric Circuits

In the lab we apply the theory learned in lecture to make circuits come to life. The lab curriculum is designed to give you a broad introduction to electronic circuits. If you have a good understanding of the lab materials you will be well equipped to embark on projects that require basic sensing and signal processing.

In the lab, all EK307 lecture sections are combined and perform the same lab activities. The lab is located in PHO 105. If there is a holiday or snow day there may be schedule delays that affect certain days only. The schedule posted below may be updated to reflect the changes. There is extra time in the schedule to ensure every lab section has a fair amount of time to complete all their labs.

## Fall 2020 labs will be hosted on Blackboard. There is a Blackboard class called ‘EK307 A1/A2/A3 Electric Circuits (Fall 2020)’. All three lecture section students will use this for the labs.
