Question:

Inductors and Inductive Reactance?

A 26.0 mH inductor has a reactance of 1.80 k. (a) What is the frequency of the ac current that passes through the inductor? ____Hz(b) What is the capacitance of a capacitor that has the same reactance at this frequency? ___ F(c) The frequency is tripled, so that the reactances of the inductor and capacitor are no longer equal. What is the new reactance of the inductor?____ k(d) What is the new reactance of the capacitor?___ k

Answer:

ok for the first one: reactance is 2pifL Xl reactance Solve for f which is frequency b. then u use 1/2pifC Xc for part b, and use this equation to get C c. Just do what it says for c and d. and use the above equations.
The inductive reactance cannot be calculated without more information.
