Can you replace a 100 amp panel with a 200 amp panel using the same wires coming from meter?

No the service wires need to be upgrade to 3/0 copper or 250 mcm aluminum. This will require a power company to disconnect so you can upgrade the service. These wires are always hot unless the power company disconnects from their source. Do it right pull a permit and upgrade
Additional information:Some meter base boxes include a shutoff/breaker. If you are only looking for additional space inside the breaker panel, and do not upgrade to a higher amperage breaker inside the meter base, you actually CAN use the same wire, provided that it is long enough to reach into the new breaker panel.The breaker of the meter base protects from the over-current condition.
If you have the shutoff in the meter base, you will obviously be able to disconnect service while you perform the necessary changes. While you are working on the service, lock-out the meter base access to prevent anyone from turning the power back on.
It is still recommended that you pull a permit and work with a qualified electrician.

What size grounding wire do you use as the 4th wire running in your conduit from your 200 amp meter box to your 200amp service panel this is the ground wire from box to box?
You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.
Does the white and ground wire connect to same ground bar in a meter base?
There should be no ground wire in the meter stack from the mast head to the meter base. If the meter base to distribution panel conduit is PVC, then a green grounding conductor must be pulled into the conduit. This green wire is independent and isolated from the neutral wire and should never be terminated together at this point. Only the line service conductors and the neutral wire go through the meter base. The neutral goes through a lay in lug. This type of lug requires the insulation to be stripped of of the wire where it passes over the lug. This stripped wire is then laid into the lug and is secured to the meter base by the removable top piece of the lug. The neutral wire remains unbroken from the mast head to the distribution panel's neutral buss bar. Using this lay in lug the watt meter picks up the neutral wire for the plug in meters operation. If your terminology is not correct and you mean the "distribution panel" instead of "meter base" then the answer is no. There are two individual buss bars in the distribution panel. In some panels there may not be an actual "ground buss bar" but ground screws lined up in a row in the back of the distribution panel's enclosure. In all distribution panels there is a neutral buss bar where all of the neutral conductors from the branch circuits connect. Do not mix the bare ground wires and the white neutral circuit wires under this neutral buss bar.
How do you calculate permanent deformation?
Deformation is calculated by using deflecto meter.
Can 220 volt be the source at the panel and 120 volt out from the panel?
No, the source voltage can not change to a lower voltage without using equipment to do so.
You can find the pH of a substance by using?
The pH of a substance can be found by using a litmus indicator.
Is starting current of a AC Motor measured as RMS or PEAK?
IT DEPENDS WHAT MEASURING INSTRUMENT YOU ARE USING. RMS - IF USING THE CLAMP AMMETER OR PANEL METER OSCILLOSCOPE - BOTH CAN BE READ

How does a pm unite compare to a meter?
pm is short for pico-meter, or 10-12 meter. That's a trillionth of a meter (using the short scale), or a billionth of a meter on the long scale.pm is short for pico-meter, or 10-12 meter.

What is the advantage to the panel cooker?
A panel cooker is a way of using solar power to cook an item. The advantage of using a panel cooker is that it is using solar energy and not electricity.
How do you calculate a meter?

How do you fix a car horn that won't turn off?
You need to determine whether the horn button or the horn relay has failed using a voltage meter and replace the damaged part.

How can you measure a square meter?
Using a meter stick, measure out a meter. Then turn pi/2 radians according to the unit circle and measure out another meter.
Why does my 110 volt plug test 167 volts?
This depends on where the power is coming from - and how you are measuring it. If the power is coming from an auxiliary generator, the generator's motor is running too fast. If the power is coming from the electrical company: (a) You might be using a poorly calibrated meter to measure it (you are getting the wrong answer from the meter) OR (b) You have a true problem with your electrical power and need to get either the power company or an electrician in pronto to fix it. If the voltage coming in to your house is TRULY 167 volts, you run the grave risk of damaging things connected to it.
