500mA = 500 miliamper
1000mA = 1 amp so 500mA = .5 amps
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
No. 0.83 Amperes = 830 milliamperes. 1A = 1000mA, it's a base-ten system, just like meters or liters.
150 mA is.
"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.
p=i square x r = 500ma * 500ma = .25 * 4.7k = 1175 watts
Yes, you can recharge a 6V 500mA battery with a 6V 300mA charger. The charger with lower current (300mA) may take longer to fully charge the battery compared to a 500mA charger, but it should still work. Just ensure you do not exceed the voltage rating of the battery.
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.
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.
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.
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
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)
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.
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?
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!
