how do i step and rectify a 240v ac to 5 or 6v dc
with the use of a transformer, bridge rectifier, and a voltage regulator (+ a few other components, such as a fuse, etc.)..... or buy a wall wart that will give you the proper voltage output that you need.... much easier and safer for beginners.....
As BMorse said, "wall warts" or plug supplies are a great way for beginners to get a safe and inexpensive power supply started. Many are not regulated. If you find one that's rated for 9v-12v at 500mA to 1A, you can add a couple of capacitors and a 7805 fixed voltage regulator with a heat sink attached to make a very cheap 5v regulated supply. It won't be terribly efficient, but it will work.
I moved the post to the home work help.
I got this in an e-mail:
I do not answer in e-mails.
Here is a page of the EDUCYPEDIA on powersupplies:
There you will find a lot of information in the links.
As it is home work, can you show us what your plan is?
