First, get the circuits around the house tested to make sure it's happening everywhere.
You should call the power company to check the connections where your electrical service enters your house. (Meter base and breaker panel). It could be a loose connection. Do not check this yourself without getting it approved by the power company, and only if the service has been disconnected at the pole.
Removing their meter seal yourself can result in disconnection of service, fees, and criminal prosecution for theft of service. Also, it's much safer to let them check it, since they are qualified professionals.
The amperages in a service conductor can burn you to death if they are accidentally shorted, even momentarily. Electric arc flash can reach 30,000 degrees F.

Call the utility company to check the supply to the house. If it is ok to the meter base and breaker panel, your house wiring is to blame

Ask the utility company to feel the transformer wiring connections. They can be extremely hot because of corrosion and this will cause flickering power sometimes.

Check the circuit breakers.
I had a friend who's lights were flickering. He had several people look into it. Electrician, Utility etc. No luck. We spent some time turning off breakers and we came to the realization that the circuit breaker's contact was bad. Replaced the breaker and voila no flicker.

Troubleshooting is the height of the electrician's art.
The only reason there is "not enough voltage" somewhere is because there is a partially open connection providing resistance and a location to allow a voltage drop [bad splice, bad switch, bad breaker, broken wire, burned splice, ...].
It is the knowledge of how electricity works, and of the methods and materials used to create a functional wiring system, that enables a skilled troubleshooter to locate the problem and repair it.
Where should the "voltage" be, and how does it get there?
When you understand that, you will understand what is keeping it from getting where it should be...

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
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Service Voltage fluctuation may be a Power Quality problem for your electric utility to review and correct. There are some items for you to go over and help narrow the source of the anomaly. First take the middle of the road, average service composition; it is a 200 Amp, 240 Volt, 3-Wire service. Your service may not fit this description to a tee for the following reasons:
As already suggested, find out if the problem is in one circuit (breaker), the service panel, or the service drop.
Why would you want to do that -where would you obtain a lower voltage supply suitable for supplying a residence.
Electrical connection issue.
the voltage regulator
Because the higher voltage would be dangerous domestically.
You would get a shock if you provided a path to ground.
Because, a factory is generally bigger then a house so it would fit in more things that need voltage. A general factory would need 15,000 v where as a house would need 230 v
A resistor changes the voltage and the amperage, which can be needed in components
Check the battery voltage on your tester. The voltage on the panel is the same throughout the whole electrical system.
because the circuit has to many outlets on it
Assuming you normal house voltage is 120 volts, sounds like something is wired wrong. If you had the house (or part of it) running on generator and then took some voltage readings, you may have damaged some of the items in the house already.
A good example of an electrical conductor would be an electrical wire. These conductors are through your residence and is what carries the voltage to your appliances. Most types of metal: copper, silver, aluminium, etc, are good examples of electrical conductors.
I dont know exactly the voltage and amperage its rated to handle, but for a normal 120 volt circuit like you would find in your house it is enough to insulate it. That's why its often called electrical tape. It would be ill advised though to only use electrical tape to cover up bare wiring.
