John: ESR stand for Equivalent series resistor.

Me: OK.

John: The picture above show us that in a "capacitor", the higher the resistance, the lower the frequency-response of the capacitor. The lower the resistance, the higher the frequency-response of the capacitor.

Me: Why?

.

if (EMF = no change) // EMF stand for electromotive force.

{

if (ESR = low)

{

Current = high;

charge seperation = high.

}

if (ESR = high)

{

Current = low;

charge seperation = low.

}

}

.

John: The higher the resistane, the lower the current flow. As a result, the charge seperation of a "capacitor" is low. And then, the frequency-response of the capacitor is low. However, the inductor is different. 

.

Me: How ?

.

John: In a inductor, the higher the resistance, the higher the frequency-response of the inductor. The lower the resistance, the lower the frequency-response of the inductor.

.

Me: Why?

.

John: Because, the higher the resistance, the lower the current flow. As a result, the coercivity and hysterisis of the circuit are low. Therefore, the frequency-response of an inductor is high.
