White (40I/41I) Problem 1 [21%]: Phasors (a) Put a cross (X) by each of the expressions below which could be a phasor voltage: (b) Write expressions for the real currents for each of the following, assuming that the frequency f=60kHz and I =10mA, using the convention of the text. (Angles are in radians.) (c) Convert the following real expression to the corresponding phasors: Page 1 Problem 2 [21%]: Circuit Elements file:///C/Documents%20and%20Settings/Jason%20Raft...%20%20Fall%201995%20%20Schwarz%20%20Mid%202.htm (1 of 7)1/27/2007 5:22:42 PM EE40/40I/41I  Midterm 2 (Fall 95) (a) [3%] List two passive circuit elements that store energy: (b) [9%] Suppose that in a portion of the circuit for an electronic door opener you need an impedance having a 10ohm real part and a 30ohm negative reactive part at a frequency of 60kHz. Show two circuits that provide this. real part and a 30ohm negative reactive part at a frequency of 60kHz....
