400 mA (milliamps) is a measure of electrical current, equivalent to 0.4 amps. It indicates the flow of electric charge in a circuit, where 1 amp is equal to 1,000 milliamps. This level of current is commonly found in small electronic devices and components.
You die
Yes, you can use a 500mA charger for a 400mA device. The device will only draw the amount of current it needs (400mA) from the charger, so there is no risk of overloading it. However, ensure that the voltage of the charger matches the device's requirements to avoid potential damage.
400mA refers to the amount of current the light consumes when it is operating. It stands for 400 milliamperes, which is a unit of electrical current. Knowing the current consumption can help you select the appropriate power supply for the light.
No. Your portable radio needs 800mA to operate. Your adapter can only produce 400mA. If you make the connection the adapter will rapidly heat up and probably burn out.
Yes, you can use a 300mA power supply in place of a 400mA supply, but it may not provide enough current for the device to operate properly. If the device requires 400mA and only receives 300mA, it may underperform, malfunction, or even be damaged due to insufficient power. It's important to ensure that the power supply meets or exceeds the current requirements of the device for safe and effective operation.
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
First, there are no DC transformers, transformers work on AC. If you have an AC/DC wall converter that has an output of 7.2 v DC, and a max current load of 400mA, then you can use this to power a DC motor that requires less than (7.2 x .4 = ) 2.88 watts of energy.
if used for charging-NO if used for supply voltage-yes
To measure 250 milliamps alternating current on the Fluke 8025A, you would typically select the 400mA AC current range. This range allows you to measure currents up to 400mA, which covers your required measurement of 250 milliamps.
.5 amps equals 500 ma, which is much larger than .400 ma.If you meant between .5 amps and 400 ma, then again, .5 amps equals 500 ma, which is larger than 400 ma by a factor of 100 ma.
Answer You need the Voltage and the amps it can supply then use the magic triangle formula that is Watt = Amps X Volts say 400mA 12 volt that will work out to .4X12 = 4.8 watt
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)
