I did the things you said. And you are correct, three resistors. Apparently we made a mistake in our readings (we used volt and amp meters). That's why we couldn't understand it. And yes. We may use everything. So also a thermal camera. :)
Hello,
For our final lab we will be given a box with three wires, the neuter is missing. In the box there is a Y or delta configuration and we can use everything to find out if it is a Y or a delta configuration. So, voltmeters or watt meters, or even something like tin foil. Can someone...
