No, you need to supply the correct 18V to your speakers.
That is probably too much for the circuitry, so it might work but only for a short time.
Yes, but you are limited to the amount of current draw the 120 volt load can apply to the adapter.
Can I run 480 volt , 60 HZ motor at a 380 volt , 60 Hz system?
No, you cannot.
Yes, a 9 volt 1600 mA AC adapter can be substituted for a 9 volt 300 mA adapter. The mA number represents the highest allowable current to be drawn from the adaptor. The adaptor that you want to replace has only 300 mA maximum capacity. The new adaptor has five time the capacity of the old one which means that devices that draw up to 1600 mA can be connected to it. Depends on what you are pluging into.. if could possible run unit hot..
They are run on the vehicles 12 volt dc electrical system.
If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.
There are many electronics today that run on 12 volt DC power. The good news for anyone who is traveling is that you can use a 12 volt AC adapter 12 VAC 2A.
Yes, when converting from a 6-volt system to a 12-volt system in a vehicle, you typically need to replace the coil with one that is compatible with 12 volts. This is because a coil designed for a 6-volt system may not be able to handle the higher voltage and could lead to issues with the ignition system.
Four D batteries in series produce nominally 6 volts (1.5 volts per cell). A 12-volt supply may damage the machine built to run on 6 volts.
It won't run.
The main difference between a 12-volt armature and a 24-volt armature is the voltage rating at which they operate. A 12-volt armature is designed to run on a 12-volt electrical system, while a 24-volt armature is designed for a 24-volt electrical system. This difference determines the power and speed capabilities of the armature when used in electrical devices.
