A 2.2-nF capacitor and one of unknown capacitance are in parallel across a 10-V rms sine-wave generator.
Question:
A 2.2-nF capacitor and one of unknown capacitance are in parallel across a 10-V rms sine-wave generator. At 1.0 kHz, the generator supplies a total current of 3.4 mA rms. The generator frequency is then decreased until the rms current drops to 1.2 mA. Find
(a) the unknown capacitance and
(b) the lower frequency.

Learning entails sharing as well. Being a student, I have been sharing my knowledge since high school times because this is what enriches me. I have been on Chegg as a tutor for a long time and also provide lessons to some other students at my localities. Currently, I am also working as a Chemistry and Biology expert at Bartleby.
