You have a $195$

resistor, a $0\mathrm{.}404$ H

inductor, a $4\mathrm{.}98$ F

capacitor, and a variable$-$frequency ac source with an amplitude of $3\mathrm{.}02$ V

$.$ You connect all four elements together to form a series circuit. Part A

At what frequency will the current in the circuit be greatest?

Express your answer in radians per second. Part B

What will be the current amplitude at this frequency?

Express your answer with the appropriate units. Part C

What will be the current amplitude at an angular frequency of $405$ rad$/$s

$?$

Express your answer with the appropriate units. Part D

At this frequency, will the source voltage lead or lag the current?
