A 9v 1000ma adapter will operate a 9v 500ma device.
If the power source is 9V 800mA and the load if 9V 500mA then yes. An appliance will only draw as much current as it needs.
(8 + 3v)(8 + 3v) or (8 + 3v)2
No. The adaptor will overheat.
Thats my question?
this is an expression with a variable that is "v" 9v+74
3v2 + 9v = 3v(v + 3)
Yes, you can use a DC 9V 600mA AC adapter on a 9V 400mA scanner. As long as the device that you are plugging into the 600 ma adapter does not draw more that 600 ma it will work.
Yes you can.
3v2 + 9v = 3v (v + 3)
Yes. 3500mA = 3.5A
you better not. you need a 9V regulator for this, not a resistor!
A: No problem but don't expect the power to increase
yes, if the other adapter is a va
Yes, you can use a DC 9V 500mA AC adapter in place of 9V 400mA adapter. As long as the device that you are plugging into the 500 ma adapter does not draw more that 500 ma it will work.
You can buy 9V batteries from almost any supermarket
Yes, a 9v 1100mA power adapter work with your 9v 500mA device. The mA number is the maximum amount of amperage that the adapter will produce without overloading itself. At 500 mA the adapter will only be working at half load.
Yes, as long as the polarity and physical connectors match.
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
9v! More voltage, more strength! Many 9v batteries merely have 1.5Volt cells jammed together to make 9V!
generally yes, it can deliver 300mA, the device only requires 200mA
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
Yes, you can charge a leydon jar with a 9V battery. After all, a leydon jar is just a capacitor. A typical leydon jar is about 1nF, so you would not be able to do much with a potential difference of only 9V.
