I have built a power supply with the following order. Variac-Full Wave Bridge Rectifier-Capacitor.
I get the input from the wall. I connected neutral and line to the rectifier. Not using the ground.
The multimeter shows a steady DC output. However, I'd like to see the output with more details.
I build a really simple circuit with a resistor and an LED to test the power supply. Here is the problem! Everytime I connect the circuit to the scope the LED dies. I don't go beyond 40V out.
I tried to sketch what I have and what I am doing so far.
Any suggestions would help. Thanks in advance.
