Answer: Inductive reactance is the opposition to the change in current in an electrical circuit and is abbreviated Xl.
Answer: The opposition to current flow is called resistance (for DC), or impedance (for AC; often just called resistance); the unit for both is the ohm.
In the simplest case, that would be resistance - but there is also another type of opposition (only relevant for AC) called reactance. The combined effect of resistance and reactance is called impedance.
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
That is called an electrical current.
Think of it like this: Friction causes you difficulty in pulling heavy objects on a carpet. This frictional force is similar to electrical resistance. It is one of two ways to define how easily electricity will travel through an electrical element.
The unit for electrical current is the ampere.
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
It is nothing but giving current in opposite direction (positive to negative andnegative to positive)
"Opposition to current" can refer to resistance, reactance, or impedance.

An Ammeter is used to measure electrical current, which is measured in Amperes (or Amps).
The total opposition to current flow is called resistance. It is measured in ohms and represents the difficulty that a material offers to the flow of electric current.
The current in electrical circuits is the flow of electric charge. It is measured in amperes (A) using a device called an ammeter. The ammeter is connected in series with the circuit to measure the current passing through it.
The opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
Capacitive reactance.
I resistor is called so because it provides electrical resistance (measured in ohms). Electrical resistance describes how an electrical conductor (a wire) opposes the flow of an electrical current (flow of electrons). To overcome this opposition a voltage (a energy) must dropped (used) across the conductor (wire).
In the simplest case, that would be resistance - but there is also another type of opposition (only relevant for AC) called reactance. The combined effect of resistance and reactance is called impedance.
