Can a insulated ground wire be used in lieu of a tinned bare ground wire?
Yes, as long as it is the same size wire or larger as the hot and neutral wires.
What if the new light fixture has 2 black wires and no white wire?
lights can be wired any way round, there is no positive or negative
What is the difference and how to differentiate between neutral and hot wires if both wires have the same color?
If the electrical box is grounded, check with a tester, the "hot" wire will have a voltage to the the grounded box the neutral wire will not. If the box is not grounded, with the breaker supplying the voltage turned off, use a tester on the resistance scale to check for continuity between the wires and a cold water pipe or some other grounded medium. The neutral will have continuity between the wire and a ground the "hot" wire will not.
Which is the hot wire if there are both black and red wires?
both
You are changing a light fixture but the wires are all the same color which one is the hot wire?
A light fixture will function normally either way. The hot and neutral wires are interchangeable. DANGER! This is only true of lighting fixtures!
Is the hot wire labeled positive or negative?
Hot is positive.
Which wire is positive if one is red and one is white coming from the same place?
As a rule of thumb white wires are neutral and colored wires are hot. This cannot be taken for granted though as it can and has caused serious injury. The wisest thing to do whenever you are unsure is to just test the wire that way there are no surprises

35 ampRefrigeratorRun a hot wire to the positive wire on the radiator fan

Can you mix two hot wires and neutral in same shut-off switch?
Yes two "hot" wires and a neutral can enter into a switch box. This is done on occasions where a three wire enters a switch box, drops off one circuit for the lighting and the other "hot" wire carries on to feed a receptacle circuit.
What to do with the white wire in track light with black green and white wires if the house does not have a white one?
The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire. You will have to determine which is hot and which is neutral. You can easily do this with a voltage tester. The wire that lights the tester is the hot. When you wire the light simply wire the hot to hot, and the white and green to the other wire.
What wire is positive on a table lamp?
A table lamp using AC (alternating current) does not have a positive wire, but many will color-code the wires white and black within the circuit. <><><><> As said, no positive and negative, but there IS a hot and a neutral. The hot wire may have ridges running the length of the insulation (or be colored black if separately insulated). The hot wire connects to the brass colored screw, and feeds power to the base of the bulb. Yes, will work if reversed, but is not according to electrical code. White or unridged wire connects to silver colored screw, which connects to the shell of the bulb base.
Which is the Hot wire and which is the Neutral wire if the wires you see are a Brown a Blue and a Yellow Green wire?
Brown = Hot Blue = Neutral Yellow/Green = Ground
