Why does a battery have a negative charge?

The difference in charge causes electrons to move through the wire towards the positive terminal of the battery, where they are removed from the wire. At the same time, the negative terminal supplies more electrons to the wire, so the charges don’t continually build up at the battery terminals.

What happens if a battery is charged on a positive terminal?

This work, which is done on the electric charges that are on the positive terminal, results in accumulation of potential electrical/chemical energy (and, consequently, accumulation of charge) in the battery, since it causes the reversal of the chemical reactions that release electrons.

What is the difference between a positive and negative battery?

The positive side of a battery is only "positive" in relation to the "negative" terminal of the same battery. When you hook a wire from the positive terminal of the first battery to the negative terminal of the second, a very small amount of current will flow until the potential difference reaches zero.

What happens when a conducting wire is connected to a battery?

When a conducting wire is connected between the positive and negative terminals of a battery, one end of the wire becomes positively charged and the other end negatively charged. The difference in charge causes electrons to move through the wire towards the positive terminal of the battery, where they are removed from the wire.

What happens if you hook a negative battery to ground?

If I hook the negative terminal of battery 1 to ground (which we will arbitrarily define as zero volts), and hook the negative of battery 2 to the positive of battery 1, then the negative of battery 2 will come quickly to equilibrium at 9V relative to ground.

Can a battery be charged electrostatically?

This answer is not correct probably. The terminal of a battery can be charged electrostatically. You need to realize that the terms positive and negative are relative. The positive side of a battery is only "positive" in relation to the "negative" terminal of the same battery.
