Two parallel plate capacitors are lled with the same dielectric material and have the same plate area. However, the plate separation of capacitor 1 is twice that of capacitor 2. When capacitor 1 is connected across the terminals of an ac generator, the generator delivers an rms current of 0.640 A. What is the current delivered by the generator when both capacitors are connected in parallel across the terminals? Number I Units v An inductor has an inductance of 0.063 H. The voltage across this inductor is 54 V and has a frequency of 200 Hz. What is the current in the inductor? Number UnitsAn ac generator has a frequency of 1290 Hz and a constant rms voltage. When a 4620 resistor is connected between the terminals of the generator, an average power of 0.240 W is consumed by the resistor. Then. a 0.08 10-H inductor is connected in series with the resistor. and the combination is connected between the generator terminals. What is the average power consumed in the inductor resistor series circuit? Number I Units v A 14.5-0 resistor, a 11.4-pF capacitor, and a 16.2-mH inductor are connected in series with a 225-V generator. (a) At what frequency is the current a maximum? (b) What is the maximum value of the rms current? Note: The ac current and voltage are rms values and power is an average value unless indicated otherwise. (a) Number i Units (b) Number Units
