## What is the difference between an inductor and resistor?

resistance (r) r is a continuous circuit opposition, while the inductor (l) is in an alternating circuit.

r withstand a constant current, depends on their value of “resistance” and their power.

l resist AC / fluctuating by means of ‘back emf’ product, depends on no.

short , a resistor acts to reduce current and voltage in a circuit, while an inductor acts to a certain extent as a resistor, it also stores energy in a magnetic field from coiled coils. it withstands the variations of current passing through it by storing energy in the coils, while a resistor simply reduces the current and the voltage passing through it. one lowers the current, the other keeps it stable.

a resistor is used to reduce the current and voltage, an inductor is used to maintain the current at a constant value – to avoid damaging fluctuations.

anyway, the resistor opposes the flow of current through it and dissipates the current in the form of heat. the current does not delay or lead to the voltage applied across the resistor.

An inductor behaves differently at different frequencies. at a zero frequency (cc), it acts as a short circuit and, at a high frequency, it offers great opposition to the current flow.

not only that, the basic property of an inductor, at a given frequency, is to oppose the change of current flow through it.

the current flowing in an inductor is less than 90% to the voltage applied in this inductance.

An inductor does not dissipate power, it stores energy in the form of magnetic flux. therefore, if you connect a pure inductor to an AC voltage source, regardless of the power consumed during the positive half-cycle, it must be restored to the source during the negative half-cycle. as a sea has seen. he can not keep or dissipate power. a resistor does not have this characteristic. whatever power you can provide, it will be able to dissipate as heat, provided that the heat does not burn the resistance first. Here is a purely theoretical point of view. both are impedances.

a resistor prevents the flow of current in a conductor in a non-frequency selective manner. it also acts on each frequency component of the voltage carrying the current.

An inductor, on the other hand, is frequency selective. this means that it also hinders the flow of current, but hinders it more if the frequency is higher. Direct current will see an inductor practically as a short circuit in steady state (ideally), while a very high frequency current could not pass through an inductor. all intermediate frequencies will experience different levels of impediment. it is as if an inductor opposes any change in the instantaneous value of the current.

If you put a resistor on a DC voltage source, a constant current will be drawn. if it is an AC voltage source, a waveform current similar to that of the AC voltage will flow in the circuit.

If you put an inductor on a DC voltage source, the current will increase from zero and increase forever. If it is an AC voltage source, the output current will generally not have the same waveform as the voltage. it would tend to be flatter. there would also be a time shift associated with each sinusoid.

In addition, the structure of an inductor causes the current in all its turns to generate magnetic flux connections, which must be taken into account when analyzing a circuit. the flux due to the current depends on the central material of the inductor. if the current is so high that the core saturates, the inductance tends to behave more like a resistor.
