2. Reason quantitatively as required in various fields of interest and in everyday life

Course-specific student learning outcomes:

ET 110 Course Goals: Students will be able to apply Kirchhoff's Voltage Law (KVL), Kirchhoff's Current Law (KCL), along with component characteristics, and element equations including Ohm's Law. Students will be able to analyze DC circuits by using the laws of electric circuits and employing various techniques such as Mesh analysis, Nodal analysis, and Equivalent Resistance Combinations, along with theorems such as Superposition, Thevenin's, and Norton's theorems. Students will be able to find the parameters of AC sinusoidal waveforms and analyze series resistive-capacitive-inductive circuits with a sinusoidal source.

Academic Integrity policy (department or College):
Academic honesty is expected of all students. Any violation of academic integrity is taken extremely seriously. All assignments and projects must be the original work of the student or teammates. Plagiarism will not be tolerated. Any questions regarding academic integrity should be brought to the attention of the instructor. The following is the Queensborough Community College Policy on Academic Integrity: "It is the official policy of the College that all acts or attempted acts that are violations of Academic Integrity be reported to the Office of Student Affairs. At the faculty member's discretion and with the concurrence of the student or students involved, some cases though reported to the Office of Student Affairs may be resolved within the confines of the course and department. The instructor has the authority to adjust the offender's grade as deemed appropriate, including assigning an F to the assignment or exercise or, in more serious cases, an F to the student for the entire course."
