Which AC input transformer required for 5volt dc output power supply?

It depends on the required output current, load rejection factor, and ripple. Also, efficiency enters into the picture.

Can you use a 5V 350ma adapter to power a 4 port usb hub?
Always use the correct power adapter for your devices. Doing otherwise can and might just break or short out your device. Technically speaking that will not likely provide enough power to run a USB hub. Each of the USB ports on a powered hub must be capable of providing up to 500ma of power. So usually you'll see a 5volt 2amp or something akin to that. Many electronics store will sell a variable output power supply which allows you to set the plug and power rating on the supply to fit your needs. The hub/device will USUALLY have a list of the input power required. Hope that helps!
How are gold and silver purified?
Purifying gold and silver is probably easiest through electrolysis- silver scrap is melted into a bar and immersed into a solution of nitric acid a positive DC voltage supply (cathode) is attached to the bar the anode side or negative side is attached to a stainless steel sheet. Pure silver crystals will grow over several days on the anode. At the end of the process they are flaked off the anode and melted, yield is usually 999. fineness. voltage usually 1.5ma @ 5volt DC
Is there anyway you can test the TP Throttle Position sensor without a scan tool?
yes. with a voltage meter,but you must know what wire is your signal wire and 5volt reference.should be almost nothing at idle and up to 5volts full throttle. gm jim THIS WORKED GREAT!!! HTTP://92lude.com/idle_air_control_bypass_mod.htm
What does the power supply of a computer do?
A power supply's job is to convert an Alternating Current (AC) signal coming from your wall outlet into a usable Direct Current (DC) signal. Simply stated, this process is done by stepping down the input voltage level with a transformer and then rectifying it to convert to DC. Once the DC signal is generated it is used to power all the devices and components of your system. In order to distribute the signal around to every component, many internal or external splitters can be attached to satisfy the number of connected devices. Usually a preset number of leads are provided by manufacturers to make this splitting procedure simple or even unneeded to the end user (as proper voltage values must adhere to specifications). From there, voltage regulation (often in the way of capacitors) is used to prevent your power supply from outputting too much or too little power. This protective mechanism is often called over current protection, over voltage protection, or over power protection. It is always important to ensure that your power supply has built-in regulation capabilities or spikes / sags due to fluctuations from the supply could damage your components. Alternatively, connecting your power supply to an Uninterruptible Power Supply (UPS) unit can greatly eliminate any potential harm due to external conditions on the unit.For computers the power supply is most responsible for providing power to the motherboard, your hard drive, CD drives, expansion cards, etc. In most cases, a single PSU unit (as opposed to a redundant power supply setup where multiple PSUs are cascaded in case one fails) is responsible for powering all parts internal to the system. Some external devices such as keyboards, mice, and external drives may also draw power either directly or indirectly from the power supply. This makes the power supply a critical component to the system. That's why when the power supply fails, your system will no longer operate.
How do you find out the power supply voltage from my wall outlet?
If you're in North America, and you're using a standard PowerPoint (ie. a normal outlet - two vertical bars with a round pin beneath or above), then you've almost certainly got 110 to 125 Volts AC. If you're in Europe or many places elsewhere - like Australia, for example, then it's possible that you've got 220 to 240 Volts AC. Using a voltmeter, you can measure the voltage between the pins to determine exactly what voltage is provided. I'd get an electrician or someone technical to do this for you - the power in the electrical outlet can be DEADLY. Do not attempt this unless you're qualified to do so!
What is meaning of 8085 microprocessor?
8085 is a 8 bit microprocessor designed by Intel.
Can you use a 5 volt equal equals 550mA charger in place of a 5volt equal equals 1amp charger?
That depends what you're charging with it. If the device that you're charging originally came with a 1-amp charger, that was probably because it sometimes draws more than 550 mA while it's charging. Put it on a 550-mA charger instead, and there's a good chance that the smaller charger will either overheat or die. You can go ahead and try it ... it won't hurt the device you're trying to charge up. Set them up, plug the charger in, and don't walk away. Stay there and feel the charger every couple of minutes. -- If it's getting too hot to touch, then unplug it, and break down and buy a new 1-amp charger. -- If it just slowly gets warm, then you can probably get away with using it for short periods of time, and you can keep your device charged that way. -- If it stays cold for 15 minutes, then it means one of two things: either (1). the device doesn't need a 1-amp charger at all, and the smaller charger will keep it charged just fine, or else (2). the charger died instantly as soon as you turned it on, the device isn't charged, and you need a new charger. (In case of #2, buy a 1-amp charger.)
What happnens when a circuit is ''overloaded''?
When a circuit is overloaded, this "only" tells you that the load is greater than the design of the circuit justifies/defines as alright.We can have several manufacturers producing the same "circuit" and all of them may have slightly different "design" limitations.Example 1:A specific cable may be specified to safely provide 5 Ampere at 120 Vacyou may have 120 Vac at the beginning of the cable and after 100 yards, you might only get 115 Vac. 5 Vac is lost in the cable and is dissipated as heat. 5volt times 5 Amp = 25 Watt of heat to the cable.When this 5A limit is surpassed, ie you run 6 Ampere load on a 5 Ampere design, then the voltage will drop more. As a result, the cable will heat up more. As the cable heats up, the insulation might begin to melt. In worst case scenario this might cause a fire.Example 2:A long cable running 120 Vac at a load of 5 Ampere (or more) may have too much of a voltage drop for your equipment to run properly. This might cause equipment to malfunction or not work as well as intended.Note:Different countries have slightly different regulations regarding electrical wiring's. A cable designed for 120Vac in one country may qualify for 235Vac in another country. It may be ok for 5 Ampere load 120Vac in one country but 6 Ampere load in another country. Most cables are designed so that a little bit of overload is within safe limits.The longer the cables are, the more voltage drop and the more effect is lost in the cable. Long cables should not be overloaded, where as really short wires do not always pose as a risk even with 50% overload. (Generally less than 10 yards of cable).Stay protected though, and do not work cheaper "overloading" solutions in your house.A:An overload is when to much load is put on a circuit (too many lights or plug and cord connected loads, or motors working to hard), when this happens either the overcurrent protection device (fuse or circuit breaker) will open or in the case of motors an overload device will open the circuit. If these protective devices do not open the circuit properly the wires (or motor) will overheat and start a fire. The ampacity of a cable is rated lower than what the cable can actual carry before it fails, this is a built in safety that allows the protection devices time to operate properly.
