MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A transformer may be used to provide maximum power transfer between two AC circuits that have different impedances Z, and Zy. This process is called impedance matching (a) Show that the ratio of turns N/N, for this transformer is N N = (Submit a file with a maximum size of 1 MB.) Choose File No file chosen This answer has not been graded yet. (b) Suppose you want to use a transformer as an impedance-matching device between an audio amplifier that has an output impedance of 6.37 k) and a speaker that has an input impedance of 6.37 2. What should your N/N ratio be? Additional Materials eBook 5. (-12 points) DETAILS SERPSET9 34.P.002. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A 0.220-A current is charging a capacitor that has circular plates 10.7 cm in radius. The plate separation is 4.00 mm. (a) What is the time rate of increase of electric field between the plates? V/(m.s) (b) What is the magnetic field between the plates 5.00 cm from the center? 4.
