Formulas and description for RL in parallel

The total resistance of the RL parallel circuit in AC is called impedance Z. Ohm's law applies to the entire circuit.

Current and voltage are in phase at the ohmic resistance. The inductive reactance of the capacitor lags the current the voltage by −90 °.

The total current I is the sum of the geometrically added partial currents. For this purpose, both partial flows form the legs of a right triangle. Its hypotenuse corresponds to the total current I. The resulting triangle is called the current triangle or vector diagram of the currents.

Conductance triangle

When connected in parallel, the partial currents behave like the conductance values of resistances.
