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.

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.
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.
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.
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 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.

Will a 7.5 V 1500 mA power adapter work with your 75 V 1600 mA device?
No it will not. The adapter with an output voltage of 7.5 volts will not even come close to operating a device that requires a 75 volt supply. The best thing you can try is to find an adapter that will output the 75 volts that the device needs.
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).

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.
What will be the effects of using a 12V 1.5A power source to a 15V 1A device?
Most likely, yes. If your device requires 12 volt and draws 1 Amp of current, a 12 volt power supply will give the required voltage and will be able to supply the 1 amp of current it needs to run. A power supply that supplies a little more voltage might also work but depending on the device may cause the device to fail sooner. Much more than 12 volts will most likely destroy the device and result in a burning smell and smoke. A power supply for less than 12 volts may fail to power the device or may make it run slower. This would be like using a battery in a device and as the battery gets weaker, it supplies less voltage and the device slows down or a flashlight get dimmer till it stops working. A 1.5 amp power source is capable of delivering 1.5 amp of current to the device. If the device need less (only 1 amp), it still gets the amount it needs to function. If the power supply was rated at 10 A or 100 A, the device will still only use 1 A to function. If the power supply were rated at less than 1 amp. The device might not get enough current to run.
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.
