An 80KHz sinusoidal voltage has zero phase angle and a maximum amplitude of 20 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady state current has a maximum amplitude of 0.7 mA.
a. What is the frequency of the current in radians per second?
b. What is the phase angle of the current?
c. What is the capacitive reactance of the capacitor?
d. What is the capacitance of the capacitor in microfarads?
e. What is the impedance of the capacitor?
