EEEN 221-assignment 1 × ˇ 21 assignment%201%20(20 18 2019).pdf Question 6) For the circuit of Figure 6: (10 marks) a) Use the superposition method to find V and 5 marks c) Deduce the power delivered by the voltage source (5 marks) j3002 2A Vo 30Ω 10V 5Ω 100 Figure 6 Question 7) (5 marks) A constant voltage at a frequency of 1 MHz is maintained across a circuit consisting of an inductor in series with a variable capacitor. When the capacitor is set to 300 pF, the current has its maximum value. When the capacitance is reduced to 284 pF, the current is 0.707 of its maximum value. Find (a) the inductance and the resistance of the inductor and (2 marks) (b) the Qfactor of the inductor at 1 MHz. Sketch the phasor diagram for each condition. (3 marks) 2248 27/05/2019
