Mixed resistance mix

Lecture



Mixed connection is a combination of serial and parallel connections.

THE METHOD OF EQUIVALENT TRANSFORMATIONS

Mixed resistance mix

Conversion schemes always start from the end. In this example, we first apply the parallel transform.

Mixed resistance mix

After which the scheme will look like

Mixed resistance mix

Now it remains to calculate Rack for this we apply the sequential conversion

Mixed resistance mix

By calculating Rack, you can proceed to the calculations of current and voltage on a section of the circuit.

Mixed resistance mix

4. Connection star and triangle

Mixed resistance mix

Formulas for the transition from a star to a triangle

Mixed resistance mix

From triangle to star

Mixed resistance mix

Bridge connection
The circuit is calculated by the method of an equivalent generator, if a load is connected to the output.

Mixed resistance mix

Determine Uout = φа - φв with disconnected load

Mixed resistance mix

If all the resistances are the same, then the output voltage is 0
