It's an Amp (full name Ampere)
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2×10–7 newton per meter of length.
Electric current is the time rate of change or displacement of electric charge. One ampere represents the rate of 1 coulomb of charge per second.
The ampere is defined first (it is a base unit, along with the metre, the second, and the kilogram), without reference to the quantity of charge. The unit of charge, the coulomb, is defined to be the amount of charge displaced by a one ampere current in the time of one second.

Electrical current is measured in amps. The current is equal to the voltage divided by the resistance. Voltage is measured in volts and resistance is measured in ohms. If electrical circuits were water pipes, the voltage would be the water pressure, the resistance would be the size of the pipe, and the current would be the flow rate.
Electrical power is measured in watts. The power is equal to the current multiplied by the voltage. The power can be increased two ways. If you increase the voltage, the metaphorical water comes out of the pipe with more pressure. Or you could increase the current to make more water come out of the pipe.

Amp - or Ampere, the unit of intensity of electric modern-day (the degree of electric pass), is abbreviated a or A. Watt - the unit of capacity or cost of paintings represented by using a modern-day of one ampere under a tension of one volt (abbreviated w orW). The English horsepower is approximately equivalent to 746 watts. Wattage rankings of lamps unquestionably degree the capacity intake not the illuminating capacity Volt - the unit of electromotive tension, the degree of electric tension, is abbreviated v or V, and voltage is represented by using I. The voltage (of a circuit) is the effective (astounding root-mean-sq.) distinction of ability between any 2 conductors of the circuit in contact. some structures, jointly with 3-section 4-cord and single-section 3-cord would have dissimilar circuits of differing voltages. The Nominal Voltage is the cost assigned to a circuit to conveniately designate its voltage class (e.g. a hundred and twenty volts, 240 volts, 277 volts). the easily voltage of the circuit can selection. elementary electric words Volt Amp Watt Ohm Kilowatt-hour Ohm's regulation provider Transformer GFCI single section 3 section NEC Circuit Breaker Fuse listed available categorised Overload Overcurrent Raceway floor gadget field Circuit Conductor kit Lamp AC and DC

Electric current is by definition the flow of electric charge. The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second.

1.) Ampere - A
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 x 10-7 Newton per meter of length.
Electric current is the same as electric quantity in movement, or quantity per unit time, expressed like
I = dq / dt
where
I = electric current (ampere, A)
dq = electric quantity (coulomb, C)
dt = time (s)
2.) Coulomb - C
The standard unit of quantity in electrical measurements. It is the quantity of electricity conveyed in one second by the current produced by an electro-motive force of one volt acting in a circuit having a resistance of one ohm, or the quantity transferred by one ampere in one second.
3.) Farad - F
The farad is the standard unit of capacitance. Reduced to base SI units one farad is the equivalent of one second to the fourth power ampere squared per kilogram per meter squared (s4 A2/kg m2).

Ampere is the unit of electrical current.
Volt is totally WRONG, volt is the unit for potential difference NOT current.
Ohm is also totally WRONG, ohm is the unit for resistance NOT current
