Creating a stable 5V DC supply out of 6 V (RMS) AC

[Wrichik Basu]

First of all, I would like to thank @Borek who, in post #2, mentioned the DSO138 oscilloscope. The device has really been very helpful.

Next, I have performed the experiment, based on the circuit I had posted here. These are the results from the oscilloscope:

Output of full wave rectifier bridge

After passing the output through the voltage regulator
with necessary filter capacitors
​

I can see that the average voltage is 4.43 V, the maximum being 4.83 V. 5 V is not reached. Is this an accuracy error of the oscilloscope?

Does the first picture look like full wave rectification? Check your diode orientation.

Yeah, I have seen that. Trying to figure out the issue.

Update: Fixed it.
