If you have a power supply that puts out 4.5 volts and 2 amps but the light you have only needs 4.5 volts and 1 amp will you fry the light?

It's highly possible. The difference in amperage might be minuscule but it all depends on the gauge of the wiring, the resistors, and the capacity of the board.

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.
What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?
30 volts.
How do you power a 5 V device at a 12 V power supply?
You must step it down to 5 volts. 12 volts will most likely cause damage. Radioshack, or any small parts store should have a small package DC power supply converter IC. I got one several years ago for ~1 -2 dollars. If you have a power supply that converts to 12 volts, you can use this chip in conjunction with a potentiometer to tune the output to ~1.5 - supply voltage (in your case 12 volts). This is a simple and flexible option that does not require a whole lot of know how (or cost), as long as the power required (IE current) is not beyond the rating of the IC.
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.
What supply voltage does a computer need?
It all depends on the machine PSU(Power Supply Unit), usually 80v-150v or as I have constructed before a 20v computer so it's the same as saying 'How long is a piece of string?'- The Computer power supply takes in the 120-240 volts coming from the A/C outlet and reduces it to 18 volts D.C. to run the System board and peripheral's in the case, i.e. DVD ROM, CD ROM, HDD, Graphics card and CPU fan. Your monitor as well runs on 18 V.D.C. which is again reduced from the 120 - 240 volts A.C. through the power block, (transformer).
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.
How many volts are in a light?
There are no volts in a light. A light consumes power.
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.
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.
How do you convert 12 volt trailer lights to 24 volts?
Change the trailer light bulbs to 24 volts and supply a 24 volt source to power them, in that order.
Apple computer can run on 220V from 110V power supply?
No, of course not. The power supply needs to match the 'wall power' to provide the proper voltages to the motherboard. On the bright side, most power supplies sold in the US have a slide switch to select between 110/220 volts input. It may be as simple as moving a little red switch on the back of the power supply to configure your power supply to 110 v.
Power inverter 12 volts-220 volts?
If you are looking for a power inverter then you are going to need to take a number of things into account. These power inverters are not all equal, and they will vary in price and functionality. This blog will look at how you can narrow down your search to the right power inverter for your needs.
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.
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.
Vacuum tubes used in power amplifiers the filament power supply is typically how many volts?

What is the electrical voltage from the house to the power supply?
260 volts
Can you use 12v 500mA adapter to tv antenna that has 12v 200mA?
YES!If you have a TV antenna amplifier rated at 12 Volts and 200 milliamps, you can use any power supply that will deliver at least 200 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. note: 200 milliamps is 0.2 amps. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 200ma that it needs.
