Chapter 32: Q. 71 (page 927)

The telecommunication circuit shown in FIGURE CP32.71 has a parallel inductor and capacitor in series with a resistor.

a. Use a phasor diagram to show that the peak current through the resistor is

I=蔚0R2+(1XL-1XC)-2

b. What is I in the limits 蝇鈫�0and 蝇鈫�鈭�?

c. What is the resonance frequency 蝇0? What is I at this frequency?

Short Answer

a. What is the Emf frequency f?

b. What is the value of the inductance L ?

A television channel is assigned the frequency range from 54mHZto 60mHZ. A series RLC tuning circuit in a TV receiver resonates in the middle of this frequency range. The circuit uses a 16pFcapacitor.

a. What is the value of the inductor?

b. In order to function properly, the current throughout the frequency range must be at least 50% of the current at the resonance frequency. What is the minimum possible value of the circuit鈥檚 resistance?

A series RLcircuit is built with a role="math" localid="1650111235060" 110鈩�resistor and a 5.0-cm- long,1.0-cm-diameter solenoid with 800turns of wire. What is the peak magnetic flux through the solenoid if the circuit is driven by a 12V,5.0kHzsource?

The current lags the emf by 30掳 in a series RLC circuit with E0=10V and R=50鈩�. What is the peak current through the circuit?

The tuning circuit in an FM radio receiver is a series RLC circuit with a 0.200mHinductor.

a. The receiver is tuned to a station at 104.3mHZ. What is the value of the capacitor in the tuning circuit?

b. FM radio stations are assigned frequencies every 0.2mHZ, but two nearby stations cannot use adjacent frequencies. What is the maximum resistance the tuning circuit can have if the peak current at a frequency of 103.9mHZ, the closest frequency that can be used by a nearby station, is to be no more than 0.10% of the peak current at 104.3mHZ? The radio is still tuned to 104.3MHz, and you can assume the two stations have equal strength.
