Will 200mA power supply work for 2 amp power needed?
No No No. If your supply can give .2A, and you need 2 Amps, your supply's not going to cut it.
Will 9v 300mA power adapter work with a 9v 700mA device?
No, the adapter's power output has to be equal to or greater that the current draw of the device.
Can you use a DC 9v 300MA adaptor to power a 9v 400MA device?
The voltage would match but the amount of power would likely not be enough to run the device. Under-power will not likely harm the device, but it won't work correctly. Always use the correct voltage/power for your devices!
Can a 100 mA adapter be substituted with a 200 mA adapter?
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter. Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.
Can a 9v 800ma adapter be used on a 9v 200ma device?
Yes. There's a subtle difference in the meaning of the "--- ma" labels on the two units:-- On the "device" ... the unit that uses power ... the "200ma" is the current it useswhile it's operating.-- On the "adapter" ... the unit that supplies power ... the "800ma" is the maximumcurrent that it's able to supply. Anything less than that is easy.So your adapter is OK to operate your device. In fact, with suitable wiring and a bit ofcooling, it could nominally operate 4 of them at the same time.
What is the power of a power supply?
power supply is a device that supplies electric power to electrical load
Can you safely use a universal AC adaptor set for 9V 300mA for a game that requires a 9V 700mA?
No, a power adapter must supply the same voltage, same polarity, and at least as much current as the load requires. Your adapter can only supply 300mA, which is less than the 700mA required by the load.Your game probably will not turn on and the power adapter may be damaged.
What is the use of a power supply?
power supply is a device that supplies electric power to electrical load
Which device gives the power supply in computer?
SMPS(switch mode power supply)
Can you power a 9v 700ma device with a 9v 300ma adaptor?
No. The device will try to draw 700 milliamps which will overload the 300 milliamp adapter most likely causing it to burn out and possibly catch fire.
Why power supply an output device?
because it is devices
What device requires an electric power supply?
A motor
