What else can I help you with?
Convert 12v to 3v DC?
if you have 12v dc then you can use a 4 ohm resistor
Can you use a 12V adapter in place of a 9V?
no, different voltage could fry solid state components.
Can Charge 9v with 12v dc power?
No, not possible. The charger has to go to higher volts than the battery being charged.
How many volts takes multimeter?
In Digital multimeter we use 9V Dc battery.
If your input is 6V and output is 12V then which device you use?
using dc-dc converter
Will a 12v car battery safely work for 9V 3.5A device?
No.
Can a dc 5v device use a dc 9v cord?
That's almost twice the voltage. The chances of frying your device is high.
Can you use a 14.4V 7.2A DC battery with an amplifier which requires 12V 5A DC?
No, you cannot.
Can you use 12v 1000ma instead 12v 150ma?
12v 1000mA means that the maximum output of that unit is 1000 milliamps at 12 volts. 12v 150 mA means that the maximum output of that unit is 150 milliamps at 12 volts. So if you need 150 milliamps at 12v either will do. BUT if you need over 150 milliamps at 12v then you must go for the 1000 mA unit. By the way there are 1000 milliamps in 1 amp.
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
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.
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
