Ac Circuit Formula. Z l r jx l. C is the capacitance.
P v 2 r cos ф power formulas in three phase ac circuits. P 3 x v ph x i ph x cos ф. F is the applied frequency.
The rate of change of the stored energy power dissipated in the resistor.
Ac power example no1 the voltage and current values of a 50hz sinusoidal supply are given as. Current voltage and impedance in an rlc circuit are related by an ac version of ohm s law. Reactance is the opposition of capacitor to alternating current ac which depends on its frequency and is measured in ohm like resistance. Inductive reactance capacitive reactance impedance in relation to r and x.
