Plasma RF power Calculation

With a given load( assume it is plasma) impedance of 6.55 - j87.906‎Ω and RF power P = 1KW, one can calculate a current I = Sqrt(P/R) = Sqrt(1000/6.55) = 12.35 Amps. V= Sqrt(P*|Z|) = Sqrt(88.15*1000) = 296Volts , Where |Z| = Sqrt( R^2 + X^2) = 88.15‎Ω. On the other hand, as to my understanding one may calculate V as V = I*|Z| = 12.35 *88.15 = 1089Volts. Here is my doubts, why a result from V= Sqrt(P*|Z|) is different from V = I*|Z| V = I*|Z| ? I am not of the filed electronics engineering. I would extend a huge thanks for the one who may help me . Thank you

Power is consumed by real impedances (resistors). V= Sqrt(P*|Z|) has no technical meaning, V = I*|Z| is correct.
