At resonance, the impedance of the circuit is equal to the resistance value as Z = R.

RLC series in Resonant frequency :Z = R.
In Resonant position *(L=C).
In Resonant position *(L=C).

At resonance Xl = Xc, Z = R.

At resonance xl = xc and that's why xl-xc = 0, so z = R.

At resonance Xl = Xc, Z = R enough.

In series circuit at resonance Z=R. Hence Z=R=90 ohm.

Minimum impedance at resonannce frequency z= sqrt(r8r + (xl -xc )power2 = r
wl = wl;xc = 1/wc;w =1/ sqrt(lc);
wl = wl;xc = 1/wc;w =1/ sqrt(lc);

At resonant frequency, Z=R (since L=C)
