Chapter 12 Phasors Typical MCQ’s Given the circuit diagram, determine the voltages, currents, and their ratios at the given frequency and at varied frequencies Given the circuit diagram, calculate the voltages and currents using voltage and current division, as well as node voltage and mesh current methods Concepts & Strategies Under certain conditions (see below), you can use a generalized form of Ohm’s law V=I Z where the voltage V and current I are phasors (complex numbers that carry information about both the magnitude and phase shift of sine waves) and Z is the impedance – a complex equivalent of resistance (see below) The conditions are: 1. All sources in the circuit should be sinusoidal, at the same frequency ω 2. All circuit elements should be linear 3. The circuit should be in a sinusoidal steady state (all transients already vanished). In general, the impedance Z is a complex number, which means that voltage V and current I may have different phase angles.

### What students are saying

• 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.
