Resistance is like frictional force. It opposes flow of electricity. So this will consume some electricity in the form of heat. Measured (in Ohm) Inductance (in Henry) nd capacitance (in farad) stores energy in their electromagnetic nd electrostatic fields respectively. They don't consume any power. But in real scenarios due to the element's internal resistances used in design they usually have a drop. But these two have important spot in engineering. Both of them effects the powerfactor in the circuits.
Resistance is when voltage & current stay in phase, and it follows basic Ohms law. It is considered as 'real'.
Reactance is when Voltage & current are 90deg out of phase. Depending on whether it is +90 (lead) or -90 (lag) it is called an inductive reactance or capacitive reactance. Reactance is normally denoted by the imaginary operator 'j'
Impedance is a combination of both of the above. It is usually rep as a complex number like 2 - j3.5.
The phase angle between V & I could be any value

What is the Relationship between resistance and inductance in a RL circuit?
What is the Relationship between resistance and inductance in a RL circuit?
What is the relationship between resistance and capacitance in a clc circuit?
The relationship between resistance and capacitance in a clc circuit is the capacitive reactance given by XC.
What is the phase shift between voltage and current when an capacitance is connected to the circuit?
The amount of phase shift depends on the resistance that is also present in the system. In an ideal situation, the phase shift would be +90 degrees, but that would require a voltage source with zero resistance, conductors with zero resistance, and an ideal capacitor that exhibited only capacitance.
What is the difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
Definition of a capacitance in mosfet?
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.

What is the Relationship between resistance and inductance in a RL circuit?
What is the difference between inductance and capacitance?
both are AC sensitive phenomena.. and opposite of one another..
What is the relationship between resistance and capacitance in a clc circuit?
The relationship between resistance and capacitance in a clc circuit is the capacitive reactance given by XC.
What is the Relationship between power factor and current?
When voltage and current waveforms are out of synch the power factor is reduced. In a pure resistance load the PF is 1. When inductance and capacitance is involved the PF is from 0 to 1.
What is the phase shift between voltage and current when an capacitance is connected to the circuit?
The amount of phase shift depends on the resistance that is also present in the system. In an ideal situation, the phase shift would be +90 degrees, but that would require a voltage source with zero resistance, conductors with zero resistance, and an ideal capacitor that exhibited only capacitance.
What is difference between lumped and distributed elements?
simply defining Lumped elements are components available in market i.e., resistors,capacitors,inductors...... Whereas Distributed elements are inbuilt property( resistance,capacitance,inductance )of a connecting wire
What is the difference between LC and RC filters?
LC means coil capacitance circuit RC means resistance capacitance circuit
Relationship between resistance and capacitive reactance?
There is no physical relationship between resistance and capacitive reactance. But if someone tells you that the impedance of something: Z = 3 -4j, the real resistance is 3 and the reactive capacitance is -4.
Why do you rate a dc machine in watt but a transformer in kilo volt-ampere?
The difference between watts and volt-amperes is due to the relative phase angle, or power factor, between voltage and current. In a DC system, the two are in phase. In an AC system, with only resistance, the two are also in phase. Add capacitance or inductance and the phase angle changes.
Define capacitance with respect to physical structure and electrical function?
Capacitance is a measure of a component's ability to store electrical energy in an electric field formed between two conductive surfaces separated by an insulating material, known as a dielectric. It is determined by the size of the conductive surfaces, the distance between them, and the properties of the dielectric material. Capacitance is typically measured in farads (F) and is used to store and release electrical energy in electronic circuits.
What is the difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
