The number 120 is an arbitrary number. It could be anywhere from 208 volts up to 240 volts in a lot of cases. The 120 is used to differentiate from 230 volts. Actually the 220 volts feeds a house in three wire leads that provide a 220 and 110 volt supply to your home. In the electical box wires can feed 110 volt light sockets ,and outlets and 220 volt for stoves and air conditioners. If you have 118 volt - you have a bad connection or the wire feeding your house is too small a size, or you have too many grass growing lamps.
Sorry, I meant 108 to 140 volts and that's not written in stone. I see lower than 108 and higher than 140 in my area all the time. I think you should contact the power generating plant and your supplier. This seems like a bad case of poor control and regulation of their output and demand system. If this has caused problems for you report it to your local newspaer for investigation. Let them do the leg work.
I'm afraid it would fall on deaf ears. It's been this way since I mover here 25 years ago.

Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
Example of electric potential?
120v
Where can you find a 120V power cable?
You can find a 120V power cable at your local hardware store. Look in the section under extension cords.
Are 120V and 208V the same?
no 208v is bigger
Can 240V washer run on 120V outlet?
No.
what is the resistance of circuit with 120v and 10A?
12
What is voltage in Mexico city?
It is 120V/60Hz
What makes a 480 motor with up down and stop 120v switch work?
I think I understand what you are asking. 3-phase motors usually are equipped with a starter or contactor, since all 3 hot wires need to be switched. The control voltage that runs the starters is 120V, because it's safer and also 120V switches and relays are cheaper. You would have a 480-120V transformer (called a control transformer) in the starter box to provide the 120V "control voltage". So the arrangement you describe would have two contactors, with two phases reversed between them. Energize one, and the motor runs forward. Energize the other, and it runs reverse. The switch sends 120V to each of the contactors, which are equipped with 120V coils.
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
Why are you not getting 240v between the two hot wires?
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
Can 120V appliance work with 220V?
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
How many watts in 120v 60Hz?
You need amps
