What else can I help you with?
Can I use 4.5 volt 2 ampere adaptor instead of 5 volt 2 ampere?
yes you can.
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
When connected to a 110-volt supply, the 60-watt 220-volt lamp will consume power that is calculated using the formula P = V^2 / R, where P is power, V is voltage, and R is resistance. Since the resistance of the lamp remains constant, the power consumption would be (110^2 / 220) = 55 watts. Thus, the lamp would consume 55 watts of power when connected across a 110-volt supply.
What is mean by 600va?
VA stands for Volt-ampere. 1 VA is equal to 1 Watt. So 600va is about 600 watts. This can be confusing because a power supply rated at 600va will not put out 600 watts due to reactance. The power supply contains an inductor or capacitor so the actual output will be around 1/2 to 2/3 of the VA.
When replacing a power supply what is more important the the ampere or the volt ampere for the power output?
The question is moot, here's why: First of all, the replacement must supply the correct voltage. This cannot change. You always replace a 12V supply with a 12V supply. If the replacement supply has the correct amperage, it will also have the correct volt-amperes, since (by our definition) the voltage is the same. Say the old supply was 12V, 2A. This is a 24VA supply (12 X 2 = 24). The new supply also must be 12V, so which is more important, amperes, or VA? As you can see, if we make sure the new supply is 2A, it will also mean it supplies 24VA (12 X 2 = 24). If we make sure the new supply is 24 VA it will obviously supply 2A (24/12 = 2). So, assuming the voltage stays the same, matching either VA or amperes automatically means the other value is correct.
Potential difference is measured in a unit called 1 a volt 2 a Watt 3 an Ampere 4 an ohm?
The answer is volt.
Can you use 1 Ampere for a 2 Ampere device?
For a device the requires 2 amperes to run, a current of 1 ampere will not be enough. Such a current cannot be able to power all the components of the device to make them function properly.
Can you add 600 watt power supply to a computer that currently runs a 350 watt power supply?
Yes you should be fine. As long as it fits in the computer, you're fine. Replace the old with the new one but keep the old one in case the new one doesn't work! 300 watts is fine for replacing something smaller. You should run only one power supply at a time. What this means is that you should replace the 185 Watt supply with the 300. Having 2 separate power supplies creates the possibility of having slightly different values for ground, +5V, and +12V DC. This can cause problems with all of your computer components. Don't use both, replace the old one with the better one. <- There are some motherboards that REQUIRE two power supplies, but you probably don't have one. They're server mb's, and the reason you use dual supplies is, if one supply dies the computer uses the live one and notifies the system operator "one supply just cooked, get me a new one pls." This eliminates a point of failure. If you've got one of these mb's, both supplies have to be the same: two 300w, two 750w, whatever. Really, though, with the amount of juice some of these new video cards pull, I wouldn't even consider installing a 300w power supply in anything except a server, a lot of which are "headless"--they don't have video outs, you control them over your network. Go with at least a 500w supply, and if you might have the need for a dual-head system--two monitors are GREAT, don't let anyone tell you different--go with a 1200w supply.
What voltage is the power supply for a quest 2wire gateway model 2700HG-D?
The 2wire 2700 and 2701 models both use a 5.1 volt power supply rated 2 or 2.2 amps
Can you run a 208 volt single-phase computer off 240 volt power?
No. The 1-phase 240 setting on your computer's power supply is for the 240V wall outlets in other countries. The 240 outlets in your home are 2-phase 240.
Why transformers are called in MVA?
1. POWER TRANSFORMERS ARE "RATED" IN MEGAVOLT-AMPERES" NOT "CALLED" 2. SMALL TRAFO ARE RATED IN VOLT-AMPERE (VA) --- 0 TO 999 VA 3. DISTRIBUTION TRAFO ARE RATED KILOVOLT-AMPERE (KVA) --- 1000 TO 999,999 VA 4. POWER TRAFO ARE RATED MEGAVOLT-AMPERE (MVA) --- 1,000,000 VA UP POWER = VOLTAGE X AMPERES = VA POWER = VOLTAGE X AMPERES X P.F.(1) = VA IT IS NOT RATED IN WATTS/KILOWATTS/MEGAWATTS FOR THE LOAD IS NOT DEFINED FOR THE END USERS OR DESIGNERS AND THE POWER FACTOR IS ALSO UNKNOWN. TO BE SAFE, THEY USE 100% P.F. (UNITY) OR 1 FOR RESISTIVE LOAD THATS WHY THE RESULT IS ONLY VOLT-AMPERE. MOTOR OR INDUCTION LOAD ARE USUALLY LESS THAN 1.
Can you use 110 volt printer with 220 volt?
You need a step down voltage transformer that converts 220 volt to 110 volt to use a 110 volt printer with 220 volt. You can get good quality transformers at East West International in Houston, TX. If you order online or over the phone, they can ship it to you in 2-3 business days.
How do you change a 4 V DC 2 Amp power supply to 4 V DC 200 mA?
As Dave says there is no obvious reason to do so. However if you put a 200mA fuse or circuit breaker in series between the supply and the load you will protect the load from pulling more than 200mA from the supply should the load malfunction. That way the load is protected from damaging itself (if that was your concern).
