Determine equivalent resistance between two terminals?
Hi,
I'm preparing for an upcoming electrical engineering exam and I'm stuck on task C, which asks me to determine the resistance between 1 and 2.
How exactly do you do that? Well, I know you have to turn off all sources first and then redraw the circuit if necessary and determine the resistance, but I'm not sure how to redraw the circuit to determine whether it's a series or parallel circuit.
I have already solved tasks a and b.
I would be grateful for any tip.
Thank you in advance
best regards

Source "switch" means: short-circuit voltage source and open current source (empty run). That's all that looks pretty simple, right? Thus, the adversary at the top right already falls out completely ….after, for example, a star-three conversion could make the overview easier for you.
Thank you for the answer. And what would that look like? So would you redraw the circuit or do the conversion directly in the given circuit?
For example, one could also determine the short-circuiting drum and then calculate the internal-wide level with the empty-running voltage. But, unfortunately, I couldn't calculate the short-circuit current here. Do you know how that works?
