Can't understand why oscilloscope requires incomplete circuit in order to measure voltage in...
If I build (a very poor) transformer (for pedagogic use) using a few windings of wire for the primary and secondary coils, and use a signal generator on the primary side, I can measure the voltage on the … If I use a commercial transformer whose secondary coil has a high inductance, then I can measure the voltage across the secondary in the usual way, by connecting one oscilloscope probe to one side of the …
