You have a 208%u2212%u03A9 resistor, a 0.400%u2212Hinductor, a 4.91%u2212%u03BCF capacitor, and a variable-frequency ac source with an amplitude of 3.09V . You connect all four elements together to form a series circuit.
A. At what frequency will the current in the circuit be greatest?
B. What will be the current amplitude at this frequency?
C. What will be the current amplitude at an angular frequency of 399 rad/s ?
D. At this frequency, will the source voltage lead or lag the current?
