On a 30 amp circuit, you would use a #10 copper ground. The ground never has to be larger than the ungrounded conductors.

What is the minimum ground wire size for a 20 amp 110 volt circuit?
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
What size wire do you need for 42 amp circuit?
8 AWG copper.
How many ground wire for a multi wire circuit?
One
Is a cu wire a ground wire?
The type of wire does not generally determine whether something is a ground wire or not. A wire is a ground wire if it is connected to the ground of a circuit, or the common ground (the reference point of a circuit that is at 0 volts). However, in relation to the grounding rod used to connect the main circuit panel for a house, the rods are almost always made of steel that are copper plated.
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
Number 10 thnn copper wire.

What size wire do you need for 42 amp circuit?
8 AWG copper.
What is meant by the ground in an electric circuit?
The ground in an electric circuit is the brown copper wire.

What size wire do you need for 220 feet?
Cannot answer this question. Will need to know the voltage and amperage of the circuit. Also need to know the application i.e. is it a lighting circuit or a motor circuit?

What size wire and breaker do you need for a 200 amp continuous duty circuit?
AWG 2/0 copper wire.
When installing a new 15A GFCI circuit for a whirpool bath what size ground in addition to 12-2 wire is required?
It should be on a 20 amp breaker with #12 THHN wire. The grounding wire is typically permitted to be one size smaller, so #14 AWG bare or green wire for ground.
Why does an electrical circuit have a copper wire?
If you mean a bare copper wire, that is the "ground" wire.
Is it safe to go from 12-3 wire to a 14-2 wire in the middle of a switch leg?
No. The wire size is dependent on the circuit protection. If the circuit uses a 20 amp breaker you need to run 12 AWG wire on all devices connected to that circuit.
What size wire do you need to run 100 ft 75 amp 230 volt?
Depends on the size of the circuit which you did not list.
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
Number 10 thnn copper wire.
