u put the battries in the bottom of the train and turn it on ....!!!!!
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
There are several long lasting and dependable 9v batteries available. Duracell Coppertops are a good choice as well as Ray-O-Vac and Energizer Industrial.
this is an expression with a variable that is "v" 9v+74
3v2 + 9v = 3v (v + 3)
No. The adaptor will overheat.
3v2 + 9v = 3v(v + 3)
yes, if the other adapter is a va

A: No problem but don't expect the power to increase
you better not. you need a 9V regulator for this, not a resistor!
Using a 9V 600mA power supply to replace a 9V 1A power supply may not provide enough current to power the device properly. It is important to match the voltage and exceed the current requirements of the device to avoid damage or malfunction.
