I made a (bridge) rectifier for a simple circuit that would make several LEDs light up. When it was finished, I used a multimeter to measure the voltages between several points and got the readings you can see in this image. Why is there still an AC voltage between the two points that were supposed to be DC-only? And why is it almost twice the original transformer voltage? The resistor code is pretty blurry in the image; it's 2.2k if it helps.
