What else can I help you with?
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
For a device requireing 12v 1.5A will a DC adaptor output 12v 2A also work for this device?
Yes, a DC adaptor outputting 12V and 2A will work for a device that requires 12V and 1.5A. The adaptor can provide up to 2A, which means it can supply the necessary current without overloading. Just ensure that the voltage matches (12V) and the polarity is correct for safe operation.
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.
Will a 12v 1300ma operater a 12v 2.0 amp chair?
No, a 12V 1300mA power supply will not be sufficient to operate a device that requires 12V 2.0A. The device will not receive enough current to function properly and may be at risk of damage. It's important to match the voltage and meet or exceed the amperage requirements of a device when selecting a power supply.
Can you use output 12v 5A for 12v 3.0A?
Yes, you can use a 12V 5A output for a device that requires 12V 3.0A. The device will only draw the current it needs, so having a higher current rating in the power supply is fine. Just make sure the voltage matches and the polarity is correct.
Can you use 12V 1.5A for 7.5V 1A?
No, it is not safe to use a higher voltage power supply (12V) for a device that requires a lower voltage (7.5V). This can damage the device and potentially cause a safety hazard. It is recommended to use a power supply that matches the required voltage (7.5V) and current (1A) specifications of the device.
What does 12V-20vA means?
12V-20VA means the device requires a voltage input of 12 volts with a maximum current draw of 20 volts-amps (VA). This rating helps ensure that the power supply can deliver enough current to power the device effectively without damaging it.
Can you use 12v 600ma instead of 12v 500ma?
Using a 12V 600mA power supply instead of a 12V 500mA one shouldn't be an issue if the device connected has a current rating under 600mA. However, it's important to ensure that the voltage matches and the device does not draw more current than the power supply can provide to prevent damage.
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.
