The output of a 120 volt dimmer switch will be an AC voltage so should not be used on a DC motor.
A 24 volt heating only or a 24 volt heating/cooling (if you have ac on the unit)thermostat.
No, the battery is DC not AC.
Also called a power supply, plugs in to a standard wall outlet to provide 12 volt DC or 24 volt AC power for cameras and other low voltage devices
the 220 volt bulp in 220 volt ac current
No, auto batteries are DC not AC.
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
no
Not usually. But this depends on how the motor is made. So a permanent magnet motor is usually a d.c. Motor. It's something to do as with the wires in the motor, the electromagnet-outer fields are wound.
You will need a charger with 24 volt capability.
24 volt
That is called an inverter.
