500mA = 500 miliamper
1000mA = 1 amp so 500mA = .5 amps

Can you use a 12VCD 500mA instead of a7.5V 800mA AC power adapter?
Yes you can. But it may damage your computers power supply.
How many watts per hour will a unit that is rated at DC 12V 500mA consume?
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
Is 0.83A the same as 500mA?
No. 0.83 Amperes = 830 milliamperes. 1A = 1000mA, it's a base-ten system, just like meters or liters.
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.
Is 5.0mA the same as half an amp?
"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.
Can you recharge a 6v 500ma with a 6v 300ma charger?
No, the charger has to be equal to or greater than the device it is charging.
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 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)
Can you charge a 500mA battery with a 1300mA charger?
Yes, you can charge a 500mA battery with a 1300mA charger.
Can you use 12v 600ma instead of 12v 500ma?
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.
Can a12v 800ma adapt be used in place of a 12v 500ma adapt?
For power supplies, if the voltage is the same, the rated amperage is equal to or greater than the requirements of the device, and the plug fits, the supply is safe to use.
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
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?

Is it ok to use a 5v 1A AC adapter for a device when the original adapter is supposed to be 5V 500mA - will it damage the device?
Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than those of the device, it will be ok!
What is the output dc voltage for a nokia mobile charger?
7.5v 500mA Dc charger
Can you use 9V 500mA adapter for 9v 700mA 6.3VA device?
yes, if the other adapter is a va
