97. What is the impedance of a network composed of a 100-picofarad capacitor in parallel with a 4000-ohm resistor, at 500 KHz? Specify your answer in polar coordinates.
The impedance of a parallel RC circuit is calculated by summing the admittances of the resistor and capacitor, then taking the reciprocal. This yields a magnitude of 2490 ohms and an angle of -51.5 degrees.
