What else can I help you with?
What is power cable size for 1 kw 1 phase motor over 500 meters?
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.
What is the power rating of 500 amperes welding machine?
Welding is done with a high current and low voltage. The voltage of a 500 amp welder might be 10 v so the power rating in that case would be 5000 watts.
What is power and current if resistor is 500 ohm?
The question is incomplete without the voltage across the resistor. For example: if V (Voltage across 500 ohm resistor) = 5 Volts, then, Current, I = 5/500 Ampere = 0.01 A.
Why are power generation rated in mega watts in stead of kilo or giga watts?
You can rate a generator in any multiple you like. It's simply more convenient to express power as, say, 500 MW, rather than as 500 000 kW or as a fraction of a gigawatt. Incidentally, it's...kilowatts, not kilo wattsmegawatts, not mega wattsgigawatts, not giga watts
How many watts in 500 kv?
To convert kilovolts (kV) to watts (W), you need to know the current in amperes (A) as well. The relationship is given by the formula: Power (W) = Voltage (V) × Current (A). Therefore, without the current value, you cannot directly convert 500 kV to watts. If you have the current, you can calculate the power by multiplying 500,000 volts by the current in amperes.
Can you use a device that requires 500mA on a 1000mA adapter?
Yes, no problem whatsoever as long as the voltages are the same. The adapter's capacity is 1000 mA and your device only requires 500 mA. The draw from the adapter is only at 50%.
Will 9v 1100mA power adapter work with your 9v 500mA device?
Yes, a 9v 1100mA power adapter work with your 9v 500mA device. The mA number is the maximum amount of amperage that the adapter will produce without overloading itself. At 500 mA the adapter will only be working at half load.
Can a 12 VDC 500 mA adapter replace a 12 VDC 1200 mA adapter?
It depend on what the load of the device that plugs into it is. The mA rating is the maximum amount of amperage that the adapter can produce. The 500 mA adapter will produce about a half amp whereas the 1200 mA adapter outputs 1.2 amps. So one is about three times larger that the other. Check the device that you are trying to power for a mA load and that will tell you whether you can use it on the 500 mA adapter.
Can you use a 1A adapter instead of a 500mA adapter?
A one amp adapter is the same as a 1000 mA adapter. If your device requires 500 mA to operate then there is ample capacity in the adapter to operate a 500 mA device. Be sure to match the type of voltage AC or DC from the adapter to the driven device. Both have to be the same.
Can you use a 9V 300ma adapter to power a 6V 800ma device?
No, the mA rating of adapters is the maximum amount of load that can be drawn from the adapter. 1 amp is equal to 1000 mA. By replacing a 800 mA adapter instead of using a 1000 mA adapter is limiting the connected devices load by 200 mA. If the connected device draws 800 mA's or less then the adapter will work.
Can I substitute a 12V DC 700 ma power supply or wall wart with for a 12V DC 500 ma rated supply?
Yes you can but for devices use 12 v and 500 ma( 0.5 a) <<>> No, the output of the 500 mA power supply will be too small for a device that requires 700 mA to operate. It can be done the other way around though, a 700 mA power supply will operate a device that only requires 500 mA with 200 mA to spare.
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
Can a 5 volt 1 amp be used in a 5 volt 500 ma?
Yes, a 5-volt 1-amp power supply can be used with a device that requires 5 volts and 500 milliamps (ma). The device will only draw the current it needs (500 ma), leaving the extra capacity of the power supply unused. However, ensure that the voltage remains stable at 5 volts to avoid damaging the device.
Can use 1A power pack for 500mA device?
Yes, you can use a 1A power pack for a 500mA device. The power pack will supply the necessary 500mA the device requires, with some extra capacity. Ensure that the voltage output matches the device's requirement to avoid any potential damage.
Will a device that requires a 1.3A power supply work with a 500mA supply?
No, a 500 mA supply can only produce a half amp maximum without going into an overload condition.
Will 6v 300mA power adaptor work with a 6v 500mA device?
Most probably you are using a AC (117V or 220V) to DC 6V converter adapter. If yes, then the answer is no, you cannot use a lower current rating for a device that draws more current. If you plug in a device that needs DC 6V 500 mA to an adapter that can only supply DC 6V 300mA, then the adapter could start sending higher than 6 volts current which may damage your equipment or overheat the adapter. If you are using a higher mA rating adapter, then it's okay. For more technical details, see: http://www.jaycar.com.au/images_uploaded/plugpack.pdf
Can you use 12volts with .5A to power a 12 volts 400 mA device?
Yes, you can use a 12-volt power source with a 0.5A capacity to power a 12-volt device that requires 400 mA. The power source provides sufficient current since 0.5A (500 mA) is greater than the device's requirement of 400 mA. Just ensure that the voltage remains stable at 12 volts, as that matches the device's specifications.
