the symbol of current density is 'J'.
& its unit is (Amp/m^2)
The symbol "I " was used by André-Marie Ampère, after whom the unit of electric current is named and stands for "intensité de courant": Current Intensity.
The electrical symbol for a continuous or r.m.s. currentis an italic, upper-case, letter I. The symbol for an instantaneous value of current is an italic, lower-case, letter i.The symbol for its SI unit of measurement, the ampere, is an upright, upper-case, letter A.
Amperage refers to the amount of electric current flowingthrough a circuit and is measured in amperes, or amps. Theamount of water flowing through a pipe can be compared toamperage. Amperage is abbreviated A or I.So the answer is= "A" or "I"Unit of Electric Current is= "A"I is the symbol for current (I traditionally means intensity). Current is measured in amperes (symbol = A).Letter ' I 'Other letters used as symbols for electricity or charge:Either 'e' or 'v' for potential difference (voltage)'Q' for charge (coulombs)'R' for resistance (ohms)'C' for capacitance (farads)'L' for inductance (Henrys).Unit of Electric Current is= "A"I is the symbol for current (I traditionally means intensity).

hinders flow of current
By 'speed of electricity', presumably, you mean 'speed of current'? We don't normally measure the speed of current but, rather, its intensity. The unit of measurement of current is the ampere (A), which is one of the SI system's seven base units. The ampere is defined in terms of the force a current produces, due to the magnetic field surrounding it, between two, parallel conductors.
Mass | Unit : Kilogram | Symbol : kg. Length | Unit : meter | Symbol : m. Time | Unit : second | Symbol : s. Temperature | Unit : kelvin | Symbol : °K. Amount | Unit : mole | Symbol : mol. Electric Current | Unit : ampere | Symbol : A. Luminous Intensity | Unit : candela | Symbol : cd.
The standard unit is the ampere, commonly called "amp", symbol 'A'.

Ampere
Hi,The symbol for amps, or amperes, is A. though in the equation V=IR, current is represented by an I. the proper symbol is A.CommentDo not confuse the symbols for quantities and for units of measurement. Current is a quantity, and its symbol is an italic I. The ampere is a unit, and its symbol is an upright A.
Ampere is the unit used to measure the current.
A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the intensity of the light.
A kilowatt (1000 watts) is the unit of measurement for the current consumed per hour.
