I have a 40 volt AC transformer that I put a bridge rectifier on, and I wanted to see the input signal and the output signal on the same screen on my scope, so I set one channel up with the test lead on one side of the input and the ground lead on the other side of the input, then I used another channel on the scope and clipped the test lead on the positive side of the output then the ground on the negative side of the output.
When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier literally caught on fire.
Why did it do this? And is there any way to achieve what I want to see on my scope?
