In common practice, the principle reservoir for electric charge is a battery. Fuel cells, which are like batteries except with external reactant sources, are becoming more widely used as electric reservoirs. In pure circuit design, the capacitor is used as the charge reservoir.
The coulomb (symbol: C) is the SI derived unit of electric charge. It is defined as the charge transported by a steady current of one ampere in one second:One coulomb is also the amount of excess charge on the positive side of acapacitance of one farad charged to a potential difference of one volt:
It lacks electrons rather then having an excess of elementary particles, but basically it's an excess of protons.
Charges are produced due to a source providing some energy. e.g cell. Firstly source creates potential difference between terminals and due to this electron at negative end of the terminal move towards positive terminal. In contrast, conventional current flows from positive to negative. In AC circuit electron stay at same place and just vibrate and energy is just passed around the circuit.

due to friction temperature increases and the valence electrons get enough energy to transfer from one body to the other. The body which loose electron get positive charge due to deficiency of electron and the body which gains electron become negatively charged due to excess of electrons.

A negative charge is caused by a excess of electrons and a positive charge by their lack.
That means that there is an excess of either positive or negative electric charge.
negative
To ground an object means to connect it through a conductor to the ground, or Earth. Grounding is a way to prevent an electric charge from building on an object, or to get rid of an electric charge.
Yes the Earth has a vertical electric field that points down. So if you were to try and calculate the amount of excess charge on the Earth's surface, you would get a negative value.
An electric charge is produced when a body has deficiency or excess of electrons from the normal due share.

Negative ions have an excess of electrons while positive ions have a deficiency of electrons.
