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 opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
It is nothing but giving current in opposite direction (positive to negative andnegative to positive)
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.
Yes, resistance is the opposition posed by a material to the flow of current. It is measured in ohms and is influenced by factors such as material composition, length, and cross-sectional area of the material.
Resistance is the opposition to the flow of electric current. It is caused by collisions between electrons and atoms in a material, which leads to the conversion of electrical energy into heat. The unit of resistance is the ohm (Ω).

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.
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
I oppose alternating current. Direct is the only way for me. That is 1 in opposition.
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.
Capacitive reactance.
Resistance
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.
It is nothing but giving current in opposite direction (positive to negative andnegative to positive)
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.
The opposition of current flow is measured in ohms. For DC circuits it is resistance and for AC circuits it is impedance.
