Unformatted text preview: What is the cross sectional area of electrodes with a mylar dielectric separating the electrodes (100nm thick, mylar = 3.2) needed to fabricate a capacitor to simulate the capacitance of a human? 3. Determine the frequency (f o ), and angular frequency ( o ), at which the impedance of a 10mH inductor equals the negative of the impedance of a 50 F capacitor. As the frequency increases, which impedance becomes larger the impedance of the inductor or the capacitor? 4. Calculate the phasor notation for the following voltages. a. V(t) = 30 cos(60t + 120 o ) b. V(t) = -18 cos(1000t 30 o ) c. V(t) = 12 sin(100t) d. V(t) = -12 sin(100t) 5. Calculate the current in phasor notation that flows through the components below that has a voltage of o V 45 100 with an angular frequency of 2 (60Hz) applied across it. a. 300W b. 0.3mH c. 47 F...
