A 47 μF capacitor is placed across a 100 Hz sine wave ac source generating 12 V rms. Calculate the peak circuit current.

An RC series circuit is connected to a 120-V, 60-Hz power source. The resistor is 25 and has a voltage drop of 65 volts. What is the capacitance of the capacitor?

A 15-F AC capacitor is connected in series with a 50 resistor. The capacitor has a voltage rating of 600 WVDC. The capacitor and resistor are connected to a 480-V, 60-Hz circuit. Is the voltage rating of the capacitor sufficient for this connection?

b) Determine the voltage ??(??) and current ??(??) sinusoidal forms. Sketch one cycle of the waveforms in the same x-axis. Clearly indicating the peak value and the period of each waveform and the phase difference (in milliseconds) between the two waveforms.

Explain how you would use an oscilloscope to measure an alternating potential difference of the order of 10V peak-to-peak. (You may assume that an alternating PD of 5V peak-to-peak is available).What is the RMS value of a peak-to-peak voltage of 10.0V?

Shown in the figure below is an "RL" circuit drive by an AC power source. The AC power source has an RMS voltage of Vps (RMS) = 9.84 Volts and is running at a frequency of f = 8.585e+04 Hz. The resistor has a resistance of R = 2170 and the inductor has an inductance of L = 3.54e-03 Henries.
