On this page, the elaboration is shown of the problem on the page: series and parallel.
Because I assume that you understand the theory and have practiced it yourself, I only give a brief explanation and the answers on this page for the following circuit:
1. Determining RV of the parallel circuit:
There is a series circuit within the parallel circuit, so for convenience we add R4 and R5 together. Strictly speaking, we could regard this as the third Rv in the circuit. Because that would make the notation with the accents confusing, we leave this out.
2. Determining Rv of the series circuit:
We call the total equivalent resistance of the combined series and parallel circuit Rv’
3. Calculating Itotal:
4. Calculating partial voltages:
5. Calculating currents:
6. Calculating the partial voltages UR4 and UR5 + the complete overview.
A sum of these partial voltages must be equal to the voltage across R3.
The image shows the complete overview with currents and voltages. To practice this yourself, you can change one resistor value and go through all the steps again.
