Yes.
The cord only transmits the power. Whatever that goes in is what comes out.
No, the 220 v and 110 v systems are designed to use a different pin layout for the plugs and sockets, to avoid possibly dangerous cross-connections. The two voltages can not be mixed and equipment for one system cannot be used on the other without a transformer.
It should work okay.
A step-up transformer would be required to supply 230 volts from a 220 volts source from South Africa.
Yes it can!
Yes. If the plug (cap) end of the 250 volt lamp is compatible to the receptacle the lamp would work. The light output of the lamp would not be very bright. Because the working voltage is halved so would the light output.
No, the RPMs of the motor will be wrong and the compressor will be damaged.
No a volt is a measure of the "push" or potential. A watt (a volt times an amp) would be a measure of the work.
no

Yes
Most commonly would be lack of freon.
It should work okay.
No totally different
No, it will destroy the 3 volt device.
Yes no problem.
Yes.
Volt, even though it is a unit of work...NewtonAnswerA volt is not a unit of work. Work is measured in joules.
