What activities are lost when the electrical supply is cut off?
All activity that depends upon an electrical supply to operate will cease. To overcome this type of situation standby generators and uninterrupted power supplies are used until the electrical supply is re-established.
Why is there a positive and negative terminal in electical device?
there are positive and negative terminal in electrical device who operate on dc power supply because they wont work if the connection is reversed. but devices who operate on ac usually dosenot have polarity marks .
On a WC macerator installation the electrical supply to the unit should be wired from?
On a WC macerator installation the electrical supply to the unit should be wired from a switch.
Do electrical wires affect the voltage?
electrical wires are selected to satisfy with the desired conditions and supply.
What pushes the current around the circuit?
A voltage supply is needed to operate a circuit.
Why does proper starter operation depend on good battery cables and connectors?
A starter is an electrical device that requires the proper supply of electricity to operate properly. Weak battery or loose or corroded connections and it will not function properly.
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.

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.
What happens when a solar cell cannot supply enough current to a circuit?
the circuit might not operate properly. but shouldn't effect the circuits them self.
How do the milliamp ratings of LEDs 20ma and a 12 volt 1000ma power supply figure into the resistor equations or do they not?
A: Since you know the current flow you need the voltage drop for this particular led at 20ma. All LED require a current and voltage to operate properly assuming a voltage drop of 2v then for a 12v source it becomes 12-2=10v 10v/.02=500 ohms in series to limit the current is required
How do you check the under voltage relay?
The way you check to see if an under voltage relay is wired properly is to disconnect the electrical supply. If the device that is connected to the load side of the relay does not start up or energize when the electrical supply is reconnected, then the relay is connected correctly.
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.
Why is there a positive and negative terminal in electical device?
there are positive and negative terminal in electrical device who operate on dc power supply because they wont work if the connection is reversed. but devices who operate on ac usually dosenot have polarity marks .
Can you replace a transformer with an input rating of 120VAC 60Hz 12W and output rating of 12vdc 500mA with one that has an input rating of 120vac 60hz 25w and an output rating of 12VDC 1A?
Yes, you can. Here's why. If a supply's output is rated at 12 volts DC (12 VDC) and 500 milliamperes (500mA), it can deliver a maximum of 500mA at the 12 volt rating. You want to use a 12VDC supply that is rated at 1A (1000mA). That means that the supply is capable of delivering up to 1A at 12VDC. Now the crux of the matter. Your device, that's the load on the supply, needs 12VDC to operate. Your replacement supply is rated at 12VDC. No problem. Your supply delivered a max of 500mA. That does NOT mean that your load, that thing you're powering up, actually uses all 500mA. Your load knows how much current it needs to draw. Your supply has to be rated for more than that. Your supply was rated at 500mA. It worked well. The supply you wish to use will deliver a max of 1A (1000mA). It will easily supply the current your load will use. Oh, and the polarity of the new supply must be the same as that of the old one. That's pretty obvious. Always be safe and consult an electronics specialist for electrical questions. There are a number of savvy folks working at consumer electrical outlets who can get you up to speed.
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.
Where can one buy an electrical supply box?
Electrical supply boxes can be found from a local electrical warehouse or else try a good electrical supply store online, before you buy it should consult with a registered electrician.
