A lot of people call an electrical receptacle a "plug". If that is what is meant in this question, the answer is:
First make sure that you have the power turned off at the main breaker panel. One socket of the receptacle will needs a white wire and the other side needs a black wire. The center (ground) socket needs a green wire.
However, if this question may be asking about the connector at the end of an electrical cord which has projecting prongs (also called blades or pins) that "plug into" a matching receptacle. In that case the answer is: people have been replacing electrical plugs for years. You don't need an expensive professional electrician just to replace a plug on your radio or a lamp! The power will be off if you just unplug it from the receptacle. One prong or blade of the plug will need a white wire and the one on the other side needs a black wire. The center (ground) prong or blade needs a green wire.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

can you plug a 115 volt into a 110 volt
To wire a 230 volt contactor with a 110 volt coil, you need to connect the 110 volt power supply to one terminal of the coil and the neutral wire to the other terminal of the coil. Ensure that the contactor is rated for use with a 110 volt control circuit. Additionally, verify the wiring diagram provided with the contactor for proper connection details.
on a standard 110-120 volt recptical the larger contact is the neutrial (white)side the smaller contact is the "hot" side
No, it won't get enough power and won't work.
If you are lucky the fuse will blow. If not the refrigerator might catch fire.

There is a direct short after the switch.
115 Volt and a 110 Volt can be treated as the same thing. The electrical voltage supplied from your electric company is not exact and can be 120 Volt + or - 10%.

No, the applied 110 volt is too high for a 3 volt appliance. The appliance would burn out right away.
The bulb will be about half as bright.
No conversion needed. These are nominal voltages which range from 110 to 120 volts. It will operate fine on the outlet.
