Can you use a 12 volts 3 amp power supply on a 12 volt 500 milliamp device?

Your power supply can supply 1 A, but your device requires 2 A. So the power supply will be overloaded. So the simple answer is no.

∙ 11y agoYes. Power supplies are rated for the amount of current they can supply at a given voltage. If your device is rated for 300 mA at 6 volts, it will only draw 300 mA from the 1 amp of supply current available. Technically you could power three of these devices from the same 1 amp power supply:
.3A + .3A + .3A =. 9 A or close enough to 1 amp.

Three amps is the same as 3000 milliamps so the answer to the question is, yes.

∙ 12y agoYes, of course you can. The load determines how much current is supplied. Your load will only draw 500 mA , yet the power supply has the capacity to supply up to 3 A, so will not be overloaded.

∙ 11y agoYes you can because the power supply can supply any load at 12 volts with a current between 0 and 3 amps.

Can you reduce 12 volt 5 amp powers supply to power a 12 volt to 150 milliamp camera?
You don't need to reduce the power supply. A device will only draw as much as it needs. A power supply of 12 volts 5 amps is the same as 12 volts 5000 mA. So you see that the power supply has more that ample capacity to operate a 150 mA camera. The thing to watch for is that both supply and camera need the same type of voltage, be it AC or DC. You can not cross that up and use AC on a DC device or vice versa.
5 List three functions performed by the power supply?
Manages watts to each device Manages volts to each device Supplys power to multipul devices
What does input volts and output volts mean?
The terminology would typically reference a device such as a power supply, charger, diverter or transformer. The Input Voltage is the voltage supplied to the device to make it work. The Output Voltage is what the device supplies to an application. For example, a power supply for a laptop might convert 120 VAC to a voltage like 19.5 volts (A Sony Laptop) for charging a laptop battery.
Is it okay to use a 5 volts amp DC power supply with a device that says it needs 5 volts 2 amp?
It looks like the crucial number was left out of the question, between the words "volt ... amp DC". If the device says it needs 5 volts at 2 amp, it will run safely on any DC power supply rated at 5 volts and (2 or more) amps.
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
Is it okay to use a 12 volts 600 milliamp DC power supply with a device that says it needs 12 volts 1 amp?
No, 1 amp is 1000 milliamp your power supply will only deliver 600 milliamp or .6 of an amp.
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.
Can you use 5 volts 1.2 amp power supply on 5 volts 3.0 amp device?
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
Can you reduce 12 volt 5 amp powers supply to power a 12 volt to 150 milliamp camera?
You don't need to reduce the power supply. A device will only draw as much as it needs. A power supply of 12 volts 5 amps is the same as 12 volts 5000 mA.

Can a device requiring 12 volts and 3 amps run with an adapter providing 12 volts and 2 amps?
No. Your power supply must be able to supply rated voltage (12 volts) and rated current (3 amps).
What does input volts and output volts mean?
The terminology would typically reference a device such as a power supply, charger, diverter or transformer. The Input Voltage is the voltage supplied to the device to make it work. The Output Voltage is what the device supplies to an application. For example, a power supply for a laptop might convert 120 VAC to a voltage like 19.5 volts (A Sony Laptop) for charging a laptop battery.
How can you change the 30v1000ma power output on your acdc power adapter to a output of around 30v1ma?
Your power adapter is rated up to 30 volts at 1000ma. (1 amp.) If you have a device which only draws 1 milliamp, then it should work with this adapter, as long as the voltage is correct.
What is an Input Current 5V 1000mAh?
If a device has that as their input current, it most likely means that it requires 1000 milliamp hours of power at 5 volts. A device with this would require a 5V 1000mAh charger/power cable. This type of power output is generally given by newer smartphone chargers (e.g. Galaxy S3)

Can you use a 12v 500mA for a 12v 150mA?
Yes. If you have a device rated at 12 Volts and 150 milliamps, you can use any power supply that will deliver at least 150 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 150ma that it needs.
A power supply receives 120 volts of power from a wall outlet and converts it to?
A power supply receives 120 volts of AC power from a wall outlet and converts it to 3.3, 5, and 12 volts of DC power.
