Your Name: Lab Section (Circle One): M T W Th F Instructions and Notes • Include this sheet with your homework; circle your lab section above. • Show all work to receive full credit. • Draw a box around your final answer for each problem. • Write your name on each page submitted, and staple all pages together. • Specify units for all numeric answers. • “Book Problems” refer to end-of-chapter problems in Hambley 4th edition. • Check links on web page for answers to selected book problems. Problems 1. Book Problem P5.23 (Phasors). Hint: Use phasors. Convert each sinusoid into a phasor, add or subtract the phasors as appropriate, and convert the resulting phasor back to the time domain. 2. Book Problem P5.34 (Complex Impedances). Assume steady-state has been reached. Be sure to answer all questions in the problem. Express your answers for impedances and phasors in POLAR form (magnitude, and phase in degrees). 3. Book Problem P5.40 (Circuit Analysis with Phasors). Express your answers for impedances and phasors in POLAR form (magnitude, and phase in degrees). 4. Book Problem P5.41 (Circuit Analysis with Phasors). Express your answers for impedances and phasors in POLAR form (magnitude, and phase in degrees). 5. Book Problem P5.51 (Circuit Analysis with Phasors). Express your answers for impedances and phasors in POLAR form (magnitude, and phase in degrees).
