A 50kHz sinusoidal voltage has zero phase angle and a maximum amplitude of 10mV. When this voltage is applied across the terminals of a capacitor, the resulting stead-state current has a maximum amplitude of 628.32μA. (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? (e) What is the impedance of the capacitor?
