Alternating Current

Inductive Reactance

 

In a simple resistor circuit, we defined resistance R by

V = I R

In a similar fashion, we can write

V_L = I X_L

where V_L is the maximum voltage across the inductor and I is the maximum current through the circuit. X_L is called the "inductive reactance"; it is analogous to resistance and is also measured in ohms (). The inductive reactance is given by
