Loading...Why is the circuit interpreted as a parallel circuit in sub-task 1 and suddenly as a series circuit in sub-task 2? I deduced this from the solution, but I can't explain why it was done this way. And why was resistor R1 ignored in the calculation for subtask 3? If Uq1 remains deactivated, isn't R1…

We already have a few topics: Program 3D modeling robotics Edit photos and videos AI design Cybersecurity…
Hello… Can I also operate the ballast with 230 volts if I have a 230 volt light bulb? Thanks in advance.

und die hat 230 V gegen N.
Das heißt also ein normaler 400V Motorschutzschalter?
