F i n a l M a r k : ECTE 290 Tut 6 Student Name: All questions 1 mark unless indicated. Total 10 Marks. 1. Given an inductance L=2 H and an angular frequency ω =50 determine the impedance Z L (j ω )= j100 . 2. Given a capacitance C=0.002 F and an angular frequency ω =1000 determine the impedance in polar form Z C (j )= 0.5 -90 o 3. Determine the impedance if the inductor and the capacitor are in parallel connection Z(j )=- j0.5025 4. For a capacitor the current leads the voltage by 90 o 5. (6 marks) Find the current i(t) given v(t)=12cos3t, R=4
