resistance
It is nothing but giving current in opposite direction (positive to negative andnegative to positive)
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.
In an AC circuit, the main opposition to current flow comes from the resistance in the circuit components. Additionally, reactance, which is the opposition to the change in current flow caused by inductance and capacitance, can also play a role in limiting current flow. Finally, impedance, which is the total opposition to current flow in an AC circuit, is a combination of resistance, inductance, and capacitance.
Resistance in an electric circuit is the opposition to the flow of electric current. It is measured in ohms. Resistance affects the flow of current by reducing it, as higher resistance leads to lower current flow. This relationship is described by Ohm's Law, which states that current is inversely proportional to resistance in a circuit.
An electric current that cannot flow is called an open circuit. This occurs when there is a break in the circuit which prevents the flow of electrons from moving through the circuit.
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
Impedance.
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.

I oppose alternating current. Direct is the only way for me. That is 1 in opposition.
Back EMF.
Total resistance.
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.
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.
Assuming you are talking about an AC circuit, then the total opposition to the flow of current in an R-C circuit is called its impedance (symbol: Z), measured in ohms. This is the vector sum of the circuit's resistance (R) and its capacitive reactance (XC) -each also measured in ohms.
