Will a 15DC 1000mA power supply work on a device needing 15DC 1500mA power supply?
Your question is confusing, but if you are asking whether you can use a 9V/250 mA adapter to supply a load device rated at 5 V/1000 mA, then the rule is quite straightforward. The adapter's rated output voltage must match that of the intended load, but its rated current must exceed that of the load. So in your example, you cannot use the adapter with the intended load.

How do you troubleshoot the uninterruptible power supply?
To trouble shoot a device the problem with the device has to be stated. With a UPS the first thing to check is the batteries.
4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
What is the main function of a power supply unit?
The name tells you - it supplies power to the device it is part of.
How DC behave with Capacitor?
Capacitor contains a dielectric sandwitched between two plates. So, it act as a charge storage device. When dc supply is given,it gets charged to its maximum capacity or potential equal to the supply, and then it act as a open circuit, since it has no way to discharge.
What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
Can you use a 1000mA current when the device requires a 450mA?
Current is determined by the load. If your load device requires 450 mA, then it will draw that amount of current from the supply.
Can you use a 9v 1500ma on 9v 500ma device?
Yes. (For any pairing of power supply and device, as long as the voltages are a match (in your case: 9v), and the output (in amps or milliamps (A or mA) of the power supply IS EQUAL TO OR GREATER THAN the current required by the device (in your case 1300mA or higher) then you will be fine. Yes it is suitable: The OUTPUT VOLTAGE (5v, 9v, 12v, etc) of a power supply MUST BE EQUIVALENT to the required voltage of the device to which it is to be connected, whereas the output CURRENT (500mA, 1A, 1500mA, 2A... etc) offered by the power supply MUST BE AT LEAST EQUAL TO OR GREATER THAN the current required by the device to which it is to be connected. (in your case, for example, as long as the power supply is rated at 9v, you could use one that has a rating of 1300mA, 1400mA, 1500mA, 1A...and so-on, without any damage to either device)
Will a 120V 60Hz 275W operate properly with 12V DC 1000mA electrical supply?
No, a device rated for 120V 60Hz 275W will not operate properly with a 12V DC 1000mA electrical supply. The voltage and wattage requirements of the device are significantly different from what the 12V DC supply provides, which will likely result in malfunction or damage to the device. It is important to use an electrical supply that matches the specifications of the device for safe and proper operation.
Can you use 5v 1000ma adapter on a 45v 400ma device?
No you can not. The power supply output of 5 volts is under sized. There is no way that a 45 volt device would operate from it. You will need to find a power supply of 45 volts.
What does 500-1000mA input means?
A 500-1000mA input specification indicates that the device requires a current supply within that range to function properly. This means it can operate with a minimum of 500 milliamps and a maximum of 1000 milliamps. If the current supplied is below 500mA, the device may not work effectively, while exceeding 1000mA could potentially damage it. This specification is important for ensuring compatibility with power sources.
Can you use a 12v 1500ma switching adapter on a device requiring 12v 3.0A?
No, if your device require 3.0A, 1500ma adapter which is 1.5A is not enough, voltage wise is fine, your adapter adapter will get warm, then overheat, then very likely fail.
For a device requiring DC 9V 1000mA will a DC adapter output PLUS 5V 3A also work for this device?
No. The device requires a 9V supply capable of delivering at least 1A. You're trying to supply it with a 5V supply. Go buy the right adapter. Just because there's a physical fit, it doesn't mean the part is the correct one. If the 9V supply can supply a little more than 1A (say, 1100 / 1200 mA) then that would be acceptable. If can only supply 900 mA, it may not work correctly.
Can you use a 12v 1a adaptor for a 800ma?
Yes, 1 amp is equal to 1000ma and it will be able to operate a 850 ma device.
Can I use a 16vac 4A power supply to power 16vac 1000ma tube amp?
Yes, 1000 ma equates to 1 amp. The 4 amp power supply will have more than enough capacity to operate any device drawing 1 amp.Just make sure that the voltages match. AC voltage of the power supply to AC voltage on the device. You can not cross voltages using a DC power supply to operate an AC device, or the other way around, an AC power supply to operate a DC powered device, even though the voltage values are the same.
What happens if a 200 mA power supply is used on a circuit needing 2 amp?
If a 200 mA power supply is used on a circuit needing 2 amp it would overload the power supply. Two amps equates to 2000 milliamps. Trying to pull 2000 milliamps from a device that is only capable of supplying 200 milliamps is not advisable. The excessive current draw would most likely burn the wires open and render the power supply useless.
What is an external power supply?
A power supply that is designed to be outside the case of the computer. Most laptop computers use an external power supply rather than an internal one to reduce size and weight while the laptop runs on battery power.
Can you use a12vdc 2000ma power supply to power a 12vdc 1000ma device safely?
Depending on what type of power supply it is there are a few options.If the 2000mA rating means it'll supply up to 2000mA, you're already okay, although you should put a resistor in parallel with the device to safely dissipate extra power. You wouldn't want to exactly split the supply in case the device has current demand variations. It would probably be best to siphon off say, 750mA. Since it's 12 volts, from ohm's law: V = IR you'd want 12 = 750mA*R, or a 16 Ohm resistor. It would also have to handle the power output, where P = IV, so P = 12v*750mA = 9 W. This is a lot of power, but you could probably find such a resistor somewhere. (Try looking at sandstone power resistors)However, if the supply is powering a sealed device (eg something you wouldn't open up and tamper with), I think you'd be better off just finding the appropriate power supply.
