No. 0.83 Amperes = 830 milliamperes. 1A = 1000mA, it's a base-ten system, just like meters or liters.
500mA = 500 miliamper 1000mA = 1 amp so 500mA = .5 amps
"mA" represents "milliamp" so 5.0 mA would be 0.005 Amps, which is not half an amp (0.5 A) Milli means one thousandth so 500mA would be half an amp.
Yes you can. But it may damage your computers power supply.
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
150 mA is.
500mA = 500 miliamper 1000mA = 1 amp so 500mA = .5 amps
p=i square x r = 500ma * 500ma = .25 * 4.7k = 1175 watts
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)
Yes, you can charge a 500mA battery with a 1300mA charger.
Yes. The current rating should be the same or greater than the original. This means the adapter can supply up to 500mA; In your case it only needs to supply 200mA, so it is more than up to the job.
Using a 12v 600ma source is allowing 12 volts and 600 amps of power. If the device requires a 12v 500ma source, the larger source is acceptable. Please note that it will only be drawing on 500ma of the available 600ma.
As long as the batteries are putting out the exact same voltage, then yes you can use a battery with a higher ma rating.
If you're talking about batteries, the 1500ma one has 3x longer running time, and can be used, if it fits and the connections are the same.
Yes. As long as the voltage is the same which it is. The 800mA is the capacity that the transformer can produce safely without going into an overload state. Your original adapter was rated at 500mA which means that what ever device was plugged into it draws less that 500mA. You might notice that the new adapter is slightly physically larger. So you are safe to use the new adapter with the higher rating.
It takes about 2 hours to charge and will charge from any USB port or USB charger that delivers 500ma or more.
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
