Simple Derivation for Parameter Formula of RLC Series Connection Sinusoidal Current Circuit

摘要

Taked characteristics of series circuit, the formaula of the main parameters U,Z,P of RLC series connection sinusoidal current circuit is derived with phasor method, and got the phasor triangle of the three parameters, it can reduce the steps, and compare with Trigonometric Functions derivation, the efficiency of the solution problem is improved.
