There are two. Positive + and Negative -
Positive is carried by the proton and negative is carried by the electron.
What is usually talked about when people talk about charge is electrical potential.
At zero potential there are equal number of electrons and protons. But in the real world that seldom happens so electrical potential is correct the potential difference between the state of two objects. In other words which one has the most or least electrons compared to its number of protons. Since this is hard to count we are lucky that the excess one of the other creates an electrical field and we can measure the strength of the field as a measure of the charge. The most common device to do this is a voltmeter which measures the electrical potential difference between to conductors such as the ends of a battery. There are other devices to measure the magnitude of static electrical fields.
Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
An electric current goes through an electric circuit, if it is closed.

2 amperes
an electrical charge is measured in Coulombs, which is equal one ampere-second. That is, one ampere of current through a plane is equivalent to one coulomb of charge passing through the plane per second.Current
The kinds of electric charge are positive charge and negative charge
The two kinds of electric charge are positive and negative. Positive charge is carried by protons, while negative charge is carried by electrons. Opposite charges attract each other, while like charges repel.
The electric charge of an antineutron is zero, as it is an antiparticle of a neutron which has no electric charge.
A stationary electric charge is called an electric static charge.

An electron has a negative electric charge.
Every electric charge is surrounded by an electric field.
The electric charge of a muon is -1 elementary charge, which is the same as the charge of an electron.
The electric charges of the proton and electron are equal in magnitude (size, strength), and opposite in sign.
A buildup of electric charge in an object caused by the presence of many particles with the same charge.
Electrons are called electric charge. They are responsible for electric current.
