PHYS 204 Electric Circuits and Laboratory
For the Engineering / Advanced
Physics Track
A 4-credit course providing a basic and practical
understanding of passive electrical circuits and computer-based data
acquisition and analysis, including basic circuit laws, methods of circuit
analysis, circuit theorems, operational amplifiers, capacitors and inductors,
sinusoids and phasors, sinusoidal steady state
analysis, frequency response, and test and measurement instruments, virtual
instruments, and data acquisition
software.
Prerequisite or Co-requisite: PHYS 121 and MATH 250
The course will be offered in
two 1.5-hour lecture and two 1-hour lab periods per week.

and voltage and current dividers.
Week 3: Introduction to programming for data
acquisition.
Week 4: Methods of analysis, including linear
equations, nodal analysis, super node, mesh analysis, and super meshes.
Week 5: Circuit
theorems, including linearity, superposition, source transformations, Thevenin
and Norton’s theorems, and maximum power transfer.
Week 6-7: Operational
Amplifiers, including practical op amps, ideal op amp, voltage follower,
inverting amplifier, non-inverting amplifier, summing amplifier, and difference
amplifier.
Week 8: Capacitors
and inductors, including capacitors, series and parallel capacitors, inductors,
and integrators and differentiators.
Week 9-10: First-order

Hunter College regards acts of academic
dishonesty (e.g., plagiarism, cheating on examinations, obtaining unfair
advantage, and falsification of records and official documents) as serious
offenses against the values of intellectual honesty.
The college is committed to enforcing the CUNY Policy on Academic Integrity
and will pursue cases of academic dishonesty according to the Hunter College
Academic Integrity Procedures.
