Current flows to a midrange speaker in a loudspeaker system through a 2.2-mh inductor in series with a capacitor. (a) what should the capacitance be so that the given a voltage produces the greatest current at 1.0 khz? (b) if the same voltage produces half this current at 618 hz, what is the speaker's resistance? (c) if the peak output voltage of the amplifier is 20. v, what will the peak capacitor voltage be at 1.0 khz?

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
