1 ECE 3710 Circuits and Electronics Assignment #4 Complete the following practice midterm. TERMINOLOGY, RELATIONS & EQUATIONS (20 points) Problem 1 (10 points): Given the following definition of the quality factor, derive simplified equations for the following cases when a sinusoidal input is applied across each. period one in dissipated Energy stored energy Peak 2 π = Q (a) An inductor, L, with a parasitic series resistance, R L ; find the quality factor in terms of frequency, inductance and resistance. Show all work. (b) A capacitor, C, with a parasitic parallel resistance, R C ; find the quality factor in terms of frequency, capacitance and resistance. Show all work. Problem 2 (10 points): Assume a new device has been discovered that acts like a negative resistance (V/I = -R) , and answer the following question. If a phasor voltage of the form V m e j90° is applied at a frequency of 20 kHz, what is the time-domain current across the device, given that the magnitude of the current is I m ?
