Not for very long. If the device actually requires 2A in order to do its job, then
the adapter ... which is only designed to deliver 0.5A or less ... will get warm,
then overheat, and then fail. Possibly in as little as a few seconds.
Not reliably. Trying to drain 1.8 A from a unit only capable of delivering 1.0 A is likely to cause overheating and/or tripped fuses.
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.
Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.
The adapter's voltage must match that of the device, and its current-rating must exceed that of the device. So the answer is yes.
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.
no, it may damage the appliance.1Can_12V_2A_adapter_be_used_for_12V_1A_device, 2a adapter cannot be used for 12v, 1a device if the so mentioned parameters are input parameters of the device.Yes, a 12 volt 2 amp adapter has more that enough capacity to operate a 12 volt 1 amp device. In fact the adapter can operate devices up to a limit of 12 volts 2 amps. A device larger than 2 amps connected will tend to heat the adapter up and eventually cause it to fail.
No, if your device require 3.0A, 1500ma adapter which is 1.5A is not enough, voltage wise is fine, your adapter adapter will get warm, then overheat, then very likely fail.
If you need to use an older serial device, than a USB to serial adapter is required. This adapter has all of the required drivers programmed into it to ensure that the use of your serial device is seamless.
a VOIP adapter

A display ADAPTER is neither. The Display is an output device.
Communication device
A one amp adapter is the same as a 1000 mA adapter. If your device requires 500 mA to operate then there is ample capacity in the adapter to operate a 500 mA device. Be sure to match the type of voltage AC or DC from the adapter to the driven device. Both have to be the same.
No, twice the voltage applied to a device that only requires 6 volts will probably destroy the device. When a manufacturer of equipment states a required voltage for a device that is the voltage that must be used.
Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.
No, underpowering will not "power" the device, it will not run. You must get an adapter that is 6V and (2A or higher) will be ok as well.
switching frequency is the one which regulates the switching device in a electronic circuit,by which the output voltage can be determined or can be cntrolled
The adapter's voltage must match that of the device, and its current-rating must exceed that of the device. So the answer is yes.
