40. (a) The resonance frequency f 0 of the circuit is about (1 . 50 kHz + 1 . 30 kHz) / 2=1 . 40 kHz . Thus, from 2 πf 0 =( LC ) 1 / 2 we get L = 1 4 π 2 f 2 0 C = 1 4 π 2 (1 . 40 × 10 3 Hz) 2 (5 . 50 × 10 6 F) =2 . 35 × 10 3 H . (b) From the resonance curves shown in the textbook, we see that as

Unformatted text preview: R increases the resonance curve gets more spread out, so the two frequencies at which the amplitude is at half-maximum level will move away from each other....
