Reactance and impedance are different from each other as reactance refers to electrical resistance in which the opposition to the change in voltage which may be happening due to the capacitance or maybe in current due to inductive reactance in which the imaginary component of AC impedance. It also consists of magnetic reactance which is a similar effect in magnetism or in other words reactance is an emotional reaction to the pressure that mainly results in the strengthening or adoption of a contrary belief. On contrary impedance is mainly known as the complex-valued generalization of resistance which somehow refers to acoustic impedance which is related to the propagation of sound waves in an acoustic medium. Electric impedance is the ratio of voltage phasor to the electric current phasor a measure of the opposition to the time-varying the electric current in a circuit. High impedance works when only a small amount of current is allowed on the contrary normal impedance is approximately designed impedance. When an electromagnetic wave is related to propagation in a medium.
What are the differences between reactance and impedance?
The main difference between reactance and impedance is that reactance is used in direct current whereas impedance is used in alternating current and inductance is most obvious coiled wire as went he current flows through a wire is a circular magnetic field which is created around it as AC is the sign which always changing direction of the field in the wires is always changing so that the magnetic field of the solenoid is always changing. In other words, resistance is the opposition to a steady electric current and resistance is a measure of the type of opposition to AC electricity due to inductance where impedance e is the total consideration of both resistance and reactance. It is mentioned that both reactance and impedance are given in ohms just like resistance and impedance is an abstraction of things that are far more complicated.
What is high impedance?
High impedance in electronics means a point in a circuit which allows a relatively small amount of current per unit applied in the voltage at that time. These are low current and potentially high voltage whereas low impedance circuit are opposite and high impedance are inputs which are preferred on measuring instruments such as voltmeters and mainly in the audio system a high impedance input may be required to use in devices like crystal microscopes.
