Increase primary voltage but decraease amerage - eg double voltage and half amperage. This will double your secondary voltage. "Transformed" voltage is easy to understand by following this simple math rule.
secondary voltage divided by primary voltage = no of turns on secondary and no of turns on primary.
eg;
240v \ 12v = 20 (factor)
this means the secondary winding is 20x the primary winding. Basically thats all I know Stick to this rule for step up & step down tranforming & you'll be sweet.
A: A DC adapter is basically like a battery except it is conditioned from an AC source. To change over measure the voltage when fully operational then switch to battery that have the same voltage as the adapter. the only concern should be the power required
A transformer is a component that changes AC current from one voltage to another. A transformer consists of two coils, one connected to the input, and one connected to the output. A transformer can convert voltage up or down, depending on the number of windings on the coil. An adapter MAY include a transformer to change the voltage, but an adapter usually changes the voltage AND converts from AC to DC as well, and may have a regulator that locks the voltage to prevent a surge and other components that prevent what is called "ripple".
Alternating Current ... like in most households.The adapter is either converting DC to AC or vice versa.
No, it will overcharge the battery and overtime destroy it.
Generally speaking the specified voltage is for the rated current so if used at a lower current a higher voltage will be present at the output. You can expect up to a 20% drop in voltage when loaded. So.. a 4.5 volt source rated at an amp could very well still be putting out more then five volts loaded to a few hundred milliamps. More important to consider is when you are using a high current adapter for a low current device you may be burning it up even though the voltage seams to match. Finally your device should have a voltage range in which it operates, +10,-20% is typical. This response is for an AC adapter, DC is a little deeper since there are battery eliminators and battery chargers, and of course with both transformers get warm but smoke and fire is just wrong.
On both the primary side and the secondary side the answer is no. It's OK if the voltage is within 10% of your original AC Adapter.
No, you cannot use a 12v halogen bulb with a 6v AC adapter. The voltage of the bulb must match the voltage of the adapter for them to work properly. Using a higher voltage bulb with a lower voltage adapter can cause the bulb to burn out or potentially damage the adapter.
To check an AC adapter, first inspect it visually for any signs of damage, such as frayed wires or burnt components. Then, use a multimeter to measure the output voltage: set the multimeter to the appropriate voltage setting, connect the probes to the output terminals of the adapter, and check if the voltage matches the specifications on the adapter label. If the voltage is significantly different or the adapter shows no output, it may be faulty and should be replaced.

Step down transformer from 220 volts AC to 110volts AC
If the AC adapter gives too little voltage, the electronic device will probably not work. If it gives too high a voltage, you will probably burn out the electronic device, which will have to be replaced or rewired. If the AC adapter is too weak (provides less milli-amperes than the device needs), the AC adapter can burn out. In summary, you need to check: (a) that the adapter should have the correct voltage, and (b) that it provides the required amount of milliamperes (or more) for the device.
No, it is not recommended to substitute a 12 volt 0.5 amp AC adapter with a 7.5 volt 1 amp adapter. The voltage and amperage ratings need to match the requirements of the device you are powering. Using a lower voltage adapter may not provide enough power, and using a higher voltage adapter can potentially damage the device.
It is not recommended to use a higher voltage adapter than what is specified for your device. Using a 13V adapter instead of a 12V adapter may damage your device due to overvoltage. It is best to use the adapter with the exact voltage and current specifications that are recommended by the manufacturer.
Yes the voltage is close enough to work. What you have to be cautious about is the milliamp output of the adapter. Make sure that the output of the adapter is higher than the device that plugs into it.
The original AC adapter that comes with the Nintendo Wii is not dual voltage. However, you can purchase a 3rd party 110-220 volt ac adapter specifically for the Wii. Here is a link to a merchant selling such an adapter. http://sky2k.com/shop/nintendo-wii-universal-power-adapter-100v220v-p-279.html
not unless you want to fry your electronics
An AC adapter adapts the device that one wants to power up to the AC line. That means it converts the AC line voltage to something that can be used by the device in question. An AC adapter converts AC to DC. (In contrast, a device that runs off DC and makes AC out of it is called an inverter. An example of an inverter is the device that plugs into a vehicle's cigarette lighter and has an outlet on the other end that will permit someone to plug something like a kitchen blender into it. Great for tailgating! Don't run your vehicle's battery down....) There are times when an AC adapter is the little plug-in-the-wall thingie that converts the AC line voltage to some lesser value of AC. There are a few devices out there (usually older ones) that used their AC adapters to step down the wall voltage (115 volts AC) to 24 volts AC, 18 volts AC, 9 volts AC, or anything like that. Some new sprinkler control timers use an adapter that is an AC -to-AC step down converter. By looking at the information on the adapter, the user can see what the primary voltage is (and it's almost invariably 115 volts AC or 120 volts AC - same, same for this application) and what the secondary voltage is. As stated, the secondary is almost always DC, and if it is, the polarity is almost always indicated as well. That's so a user can tell if that little round connector has positive on the inside and negative on the outside or the other way round. (It makes a lot of difference to the device on which it is used, as one might guess.)
