M$2)(20$ points$)$ An RLC circuit is driven at a peak voltage of $5$ V at a frequency of

$450$ MHz$.$ Take R $=1\mathrm{.}7,$ C $=19\mathrm{.}3$ pF$,$ L $=6$ nH$.$

a$)$ What is the peak current through this circuit at this frequency? $[$I $=2\mathrm{.}29$ A$]$

b$)$ What is the phase difference between the supply voltage and the current at this

frequency?$[$ $=38\mathrm{.}9$o$]$

c$)$ What is the peak current through this circuit when driven at $400$ MHz$?$

$[$I $=0\mathrm{.}861$ A$]$
