No, the excessive voltage will destroy the equipment, unless the fuse trips (hopefully) ...
What else can I help you with?
Can you plug 110 volt appliance into 12 volt?
NO
Can you use a 15 volt dc adapter to run a 12 volt portable DVD player The adapter in question lists as a class 2 transformer if that makes any difference?
No. You should use the adapter specified for the DVD player. Using the wrong adapter can damage the DVD player and/or the adapter and/or cause a fire.
Can you run 12 volt DC adapter equipment with a 12 volt transformer?
The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.
Can I use 12V DC output universal ACDC adaptor with equipment that uses AC adapter 12VAC 2A?
There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.
Will a 120 volt AC to 12 volt AC adapter charge a 12 volt car battery?
No, the battery is DC not AC.
Can you run a 12 volt ac water pump with a 12 volt dc adapter?
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
Can you use a 12 volt adapter on a 15 volt device?
No you shouldn't use a 14 volt 5 amp adapter on a 12 volt 5 amp device unless you know for sure that the 12 volt device has an internal voltage regulator that will lower the voltage to the correct voltage range the device was designed to use. As long as you always take care to check the output voltage with a voltmeter first, to be sure that the voltage from the adapter is regulated, meaning that it does not rise when a lower current in amps is drawn from it, you may be able to use an adapter that gives the right voltage at a higher amp output rating than the device actually takes. (For example, it may be possible to use a 12 volt 7 amp adapter for a 12 volt 5 amp device.)
What would happen if 12 volt only appliance was plugged into 120 volt outlet?
If a 12 volt appliance is connected to a 120 volt outlet, it would likely get damaged due to the excessive voltage. The appliance is designed to run on 12 volts, so the higher voltage could overwhelm and fry its electrical components. It's important to always match the voltage requirements of an appliance with the electrical supply to prevent damage.
Can you replace 12v vdc adapter by 12v vac adapter?
No, 12 volt AC is a different from 12 volt DC. Have a second look at the 12 AC volt adapter's output label. Most adapters contain a bridge rectifier in them that makes a conversion within the adapter. An example of this is in phone chargers.
Can you use ac dc adapter of 12 volts and 2 amps for an appliance rated for 7.5 volts and 1.8 amps?
To use an adapter of this sort, its rated voltage must match the rated voltage of the appliance, and its rated current must exceed that of the appliance. So, in your example, the rated voltage is too high to be used with your appliance.
Can a 12 volt 0.5 amp ac adapter substituted with a 7.5 volt 1 amp adapter?
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.
Will a 120 volt AC to 12 volt AC adapter charge a car battery?
No, auto batteries are DC not AC.
