Determine the inductive reactance for this circuit. | |

The equation, X_{L} = 2pfL , demonstrates the relationship between inductive reactance (X_{L}), the frequency (f) of the waveform applied to the circuit, and the value of the inductance (L).

The amount of inductive reactance (XL) changes proportionally with the applied frequency (f):

| - Increasing the value of f causes X
_{L} to increase. - Decreasing the value of f causes X
_{L} to decrease. |

The amount of inductive reactance ( X_{L}) changes proportionally with the value of inductance (L):
