@Abel : Resonant freq will occur in rlc/lc ckt(f=1/2*pi*L*C) and moreover resonant freq will result only when impedance of the circuit is at its minimum in series ckt (Here the resistance is increased). arctan is inv(tan) or tan^-1.

At its resonant frequency, current will be maximum isnt it?

What is arctan? isn't it just tan?

phase shift= arctan[xc/R],
phase shift is inversely proportional to R so as R increases phase shift decreases.
