Module 4 TASK 1 Direction: Solve each item. Show and write your solutions on a long size bond paper. Emphasize your final answer by writing it inside a box. 1. A loud speaker whose inductance is 1.15 henrys is coupled to a power tube through a condenser of 2 µF capacity. To what frequency will the combination be resonant? 4. Three impedances Za, Zc, Zr are connected in parallel. If at 60 Hz, Za = 0 + j8, Zc = 0 −12 and Zr= 5 + j0 ohms. Solve for the frequency at resonance. 5. A resistance R is connected in parallel with a variable inductive reactance XL. The combination is connected in series with impedance of 5 -j2 ohms. Solve for R, such so there is only one condition of resonance as XL as varied. 6. A coil whose resistance is 100 ohm and inductance of L1 is connected in parallel with a series combination of inductance L2 and capacitance C. When w = 1 x 105, the impedance of the whole combination is 300 ohms, purely resistive. When w = 2 x 105 no current flows towards the coil. Find the value of C.
