at 240/50 volt itequates to 4amp
You die
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.
Should be just after the postive output from the battery, fuse is a 4amp and should be just a couplr of inches from the battery
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
The formula for watts is W = I x E. Watts = Amps x Volts.
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
The main difference between a 2A, 4A, and 6A battery charger is the rate at which they charge batteries. A 2A charger charges at a slower rate compared to a 4A and 6A charger. The higher the amp rating, the faster the charging speed.
This shouldn't hurt the speakers because 1.2 amps is less than 400mAh oh power. The speakers should only draw the 400mAh they need although in some cases if large capaciters are used than they may be damaged. Make sure the adapter is the same voltage and outputs in the same current (AC/DC).
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
