What is the output dc voltage for a nokia mobile charger?
7.5v 500mA Dc charger
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.
Is there any danger to powering a 12V 200mA case fan via USB at 5V 500mA max?
If wired correctly, this will not damage the fan or the USB port, as the fan will take less current at a lower voltage. The main problem with this arrangement is the fan would either not start, or would run very slowly, so probably useless for cooling anything. If you can get a 5V fan, not more than 500mA, this would be much more effective. (Note- If wired incorrectly, reverse polarity could damage both USB port and fan, short circuit could damage your USB port.)
What is an mah battery?
it is the Acronym for Milliamp hours No, not an acronym. It's just an abbreviation, which should be written mAh. A small battery's capacity is given in mAh, and is the approximate product of current and time. e.g. 500mAh means it can deliver approximately 500mA for 1 hour, or 50 mA for 10 hours etc, pro rata. Larger batteries have their capacity stated in Ah.
What is the power when there are 500mA of current through a 4.7k Ω resistor?
p=i square x r = 500ma * 500ma = .25 * 4.7k = 1175 watts
What will be the potential difference across a 50Ω resistor if a current of 500mA is flowing through it?
Potential difference equals current multiplied by resistance or E = IR therefore the answer to your question is 25 volts
There is a total of 500mA of current into five parallel resisters the currents through four of the resistors are 50mA 150mA25mA and 25mAand 100mA what is the current through the fifth resister?
150 mA is.
How do you drop 12vdc 1000mA charger to 12vdc 500mA for 12v 7Ahr battery?
The current rating on a charger ("1000 mA", "500 mA"), usually means the currentthat the charger is capable of supplying if it needs to. It's NOT the current that'salways being pumped out.If your 7AH battery needs 500 mA at some time during the charging operation,then a 1000mA charger is capable of supplying it.
Can you charge a 500mA battery with a 1300mA charger?
Yes, you can charge a 500mA battery with a 1300mA charger. The battery will only draw the amount of current it needs for charging, so it will not be harmed by the higher current output of the charger. However, make sure the charger voltage matches the battery's voltage requirement.
Can you use 500MA instead of 1Amp?
Yes, you can use a 500mA (0.5A) supply instead of a 1A supply, but it depends on the requirements of your device. If the device draws more than 500mA, it may not function properly or could be damaged due to insufficient current. Always ensure that the power supply can meet the current demands of your application for safe and effective operation.
What will happen if use a 12v 500ma instead of 12v 300ma?
Using a 12V 500mA power supply instead of a 12V 300mA power supply will likely be fine as long as the voltage matches, but the higher current capacity (500mA) means the power supply can deliver more current if needed by the device. The device will only draw the current it needs, so having a higher current capacity power supply should not cause any issues.
What does 500mA equal to?
500mA = 500 miliamper 1000mA = 1 amp so 500mA = .5 amps
What will happen if use a 12v 400ma instead of 12v 500ma?
i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)
Is 9vdc 500ma the same as 9vdc 1.5a?
No, 9VDC 500mA is not the same as 9VDC 1.5A. While both have the same voltage of 9 volts, they differ in current capacity; 500mA (0.5A) means the device can draw a maximum of 500 milliamps, while 1.5A allows for a maximum of 1,500 milliamps. Therefore, a 9VDC 1.5A power supply can provide more current than a 9VDC 500mA supply, which is important for devices that require higher power. Always match the power supply specifications with the device requirements to avoid damage.
How many mA does USB 1.1 provide?
USB 1.1 port (5V power) current is limited to 500mA.
How long will a 6.0 Amp hour battery provide 500MA of current for?
6Ah will provide 500 milliamphours for 12 hours.
