Question

See #28 and #29. The book answer for #28 is a) .283 A and b) 2.26 A and the book answer for #29 is a) .095 A and b) .012 A. I understand from the formulas why these are the answers.

Could you explain in words what is it about the nature of a capacitor that causes the current through it to increase as the frequency of the alternating emf increases?

Likewise, what is it about the nature of a inductor that causes the current through it to decrease as the frequency of the alternating emf increases?

alternating current if the frequency of the emf is (a) 1.00 kHz and Module 31-3 Forced Oscillations of Three Simple Circuits •28 A 1.50 uF capacitor is connected as in Fig. 31-10 to an ac gen- erator with Em = 30.0 V. What is the amplitude of the resulting alternating current if the frequency of the emf is (a) 1.00 kHz and (b) 8.00 kHz? 29 IW A 50.0 mH inductor is connected as in Fig. 31-12 to an ac generator with Em = 30.0 V.

   Since and discharging of Capacitor charging decreases current, then higher frequency for the capanton charge and develop to lessen time means a Sub to acking voltage against the supply charging Also, allows to lesser the îndeutor through the currewe to poss frequency the line for the more indenhor to go towards its short circul value for currew for lesse State So, more frequency
