Why is a resistor frequency independent? I had a doubt that why is a resistor, frequency independent? Since, as frequency increases the movement of electrons increases so heat increases which causes change in resistance. So my question is why a resistor offers same resistance to every frequency. Any Clarification on this is appreciated.
 A: An ideal resistor is defined as the two-terminal circuit element where the voltage across is proportional to the current through:
$V_R = R \cdot I_R$
and the constant of proportionality, $R$, is, well, constant.
A physical resistor has at least series inductance and parallel capacitance and can be modelled with ideal circuit elements as follows (for example):

So, a physical resistor has an associated $Q$ and resonance frequency, i.e., it is frequency dependent.
In radio frequency (RF) design, the frequencies of interest are high enough that the frequency dependence must be taken into account.
At much lower frequencies, e.g., audio frequencies, the frequency dependence can, in general, be ignored.
A: A higher frequency does not mean that the average drift speed ("movement") of the electrons increases. The average drift speed, which depends on the mean free path, stays constant.
A: The resistor only limits the flow of current not with $\partial I/\partial t$ example inductor it will opposes the flow of current when it will change with time means time i.e $T=\frac1f$ so frequency changes take in inductor that's why resistor is frequency independent inductor frequency dependent.
$V=IR$, but Inductor $\mathrm{e.m.f}=-L \displaystyle{\frac{\partial I}{\partial t}}$
A: Electrical resistance is the opposition to current flowing in the circuit, while the reactance is the opposition to change in current in term of capacitance and inductance
So when frequency is change current is change and when current is change it's became reactance not resistance although both have same units...
So the behaviour of resistance is independent of frequency...
I think so...
