I'm new to electronics and decided to learn something new by trying to put together a small rectifier circuit that converts 24VAC to DC. So I put together a little full-wave rectifier circuit that consists of four diodes and an LED and ran into an issue when I tried to measure the DC output...
It's weird that primarily 50% of the time the purple test point is the only color to have this issue, why purple?
