What happens if i use a 12v Dc in a device that requires 9v DC And can it be repaired?

Not a good idea. It will raise the current that could burn out components. To repair you would need to determine what was burned out and how easy it would be to replace.

If a 12V device is dissipating 50W how much load resistance does the device represent?
P = V x I I = 50 / 12 I = 4.17 R = 50 / (4.17*4.17) = ~2.88
What is the device called that changes voltage in DC IE 12v 1A to 5v 2A?
If it were just 12V to 5V we would be talking about a simple regulator. Since we are also talking about 1A to 2A, we are talking about some kind of inverter, perhaps a pulse width modulated power converter.
What would happen if you used a 19V 3.16Amp power adapter on something that called for a 12V 3Amp power adapter power supply?
You would overload and damage the device and/or the adapter.
What should be primary to secondary turns ratio for step downing 220V to 12V?
220V : 12V 55 : 3
Can you use a power supply with more amps and not fry the unit?
you will need to be allot more specific on what you are trying to do here. what is the difference in amps. what is the device Generally speaking it is good practice to only use the power supply that the device is rated for. the biggest issue you will have is this Power = voltage * current (simple version) if the power supply you had was 12v at 1 amps then you ca supply 12Watts of power if the power supply you had was 12v at 10 amps then you can supply 120Watts of power Just because you can supply 10 amps, and all you need is one, means your power supply is bigger than it needs to be. The device will draw what it is intended to draw. Just make sure the voltage matches.
What happens if 12V-1200mA supply is given to 12V-700mA device?
It will work fine as long as the supply voltage matches the device. They both must be 12V, and both usually must be the same type-- either AC or DC. The supply current must be at least as much as the device requires.
Can you use a 12v 1000mA on a device that requires 600mA?
yes this will work fine
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
Can you use a 12v power adapter when device requires 6v?
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.
Can you use 12v 600ma instead of 12v 500ma?
Using a 12v 600ma source is allowing 12 volts and 600 amps of power. If the device requires a 12v 500ma source, the larger source is acceptable. Please note that it will only be drawing on 500ma of the available 600ma.
Will a 12v 18ah battery start a engine that requires 12v 40ah?
YES
Can a 12v battery be used in a 12v device?
the answer is yes as long as the device works on dc current and not ac current if you tell me what the device is i might be able to help further
Can a 12V 2A adapter be used for a 12V 500mA device?
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.
Can a 12v 550ma device be run by a 12v 210ma supply?
No, the supplies output is too small. To run a 550mA device a supply source of 600mA and larger would be needed.
The Pentium processor requires how many volts?
its 12V.....k
What if you use a 12V 1.5mA power adapter in place of 12V 1.2 mA one?
It will take longer to charge the device
Can I substitute a 12V DC 700 ma power supply or wall wart with for a 12V DC 500 ma rated supply?
Yes you can but for devices use 12 v and 500 ma( 0.5 a) <<>> No, the output of the 500 mA power supply will be too small for a device that requires 700 mA to operate. It can be done the other way around though, a 700 mA power supply will operate a device that only requires 500 mA with 200 mA to spare.
