How to connect 3V LED to 230 V AC supply without step down Transformer by using Capacitor & Resistors?
You will need more than a Cap and Resistor. AC is not DC and LEDs are all DC. So first you have to change the AC to DC then reduce the voltage. A 3V DC power supply would be your best choice, that will have what you need. But that will include a step down transformer, a rectifier (for DC) and some filtering, caps and resistors.
I did find one old print that comes close, but you do need to add a diode for DC.

Where can I find a replacement cord for a Casio ex-z60 digital camera. can’t find it anywhere online?
I need the cord that charges the camera and also a cord that allows me to upload photos to my computer. I lost both cords. Ideally I want to order a cradle that can charge and upload it.
Please help this is not spam I really can’t find the cord. Only thing on ebay is the cord that goes into the cradle but not the cradle itself. And the cord can’t go into the camera without the cradle.

my new car stereo has a different size power supply than the old one?
I bought a new car stereo (CDE-102) for my Hyundai Accent 2001. The power connector on the original is bigger than the one on my new stereo. The Bestbuy website says that it is a fit for my car, so what to i do to fix this issue?
go to walmart and get a wiring harness for your car. one side will plug into your power connectors and the other will plug into the radio that you bought. they’re like 15 dollars.

What is the advantage of using a current and voltage regulated power supply? ?
We are planning to construct a voltage regulated power supply as our project but our teacher told us that it would be better to construct a current and voltage regulated power supply instead.We are just wondering what difference can a current regulated power supply do.
Your teacher has the right idea. If you are going to make an effort, you should try to get the maximum return for that effort.
Current and Voltage regulated sources are the mainstay of industry. They allow the maximum flexibility. The programmable variety allow the testing of all integrated circuits in all the IC factorys. Even more to the point, if you intend your power supply to survive, you will have to provide the maximum protection for it. This usually means building in current limiting circuits anyway. There is almost no difference between a current limiter and a Current Regulated Supply.
