"Circuits II" is an intermediate level, in-person course provided by The Johns Hopkins University Applied Physics Laboratory's STEM Academy. This course builds on the concepts taught in "Circuits I," aiming to impart more advanced knowledge about circuits and electronics. Students will develop skills in soldering to join electronic parts together, building more intricate circuits using resistors and capacitors, and simulating circuit designs using LTspice, an integrated circuit simulation program. The course also delves into audio signals and amplifiers. The course is strictly in-person and there is no work required outside of class time. However, the specific schedule details for the "Circuits II" course are not provided in the available information. To participate in this course, students must have satisfactorily completed the STEM Academy "Circuits I" course, as it serves as a prerequisite. The course is part of the STEM Academy's initiative to foster a supportive environment for learning more about STEM skills and careers, with instruction from practicing APL computer scientists, engineers, and other STEM professionals. Upon completion, students are expected to have gained advanced skills in circuit design and electronics, contributing to their technical growth. The course carries a cost of $49.00.
