Name_________________________________ Section________________________ PHYS 1200 Lecture 7 Student Worksheet: AC Circuits 1) A sinusoidal voltage of constant amplitude V=1V and varying frequency is applied two resistors in series. For the circuit to the right, sketch your prediction for the amplitude of the voltage across the capacitor as a function of frequency. (Let R2=R1/2.) 2) A sinusoidal voltage of constant amplitude V=1V and varying frequency is applied across a resistor and capacitor in series. For the circuit to the right, sketch your prediction for the amplitude of the voltage across the capacitor as a function of frequency.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
