Calculate the change in flux of an inductor having inductance 4000 H,

1.	Calculate the change in flux of an inductor having inductance 4000 H, number of turns is 200 and the current changes from 5A to 7A.(a) 20 Wb(b) 40 Wb(c) 60 Wb(d) 80 WbI had been asked this question in my homework.This interesting question is from Ferromagnetic Cored Inductor in a DC Circuit in chapter Inductance in a DC Circuit of Basic Electrical Engineering
Answer» The CORRECT choice is (b) 40 Wb To explain: From the FORMULA of incremental inductance, we know that: L=(Change in flux/Change in current)*Number of turns Substituting the values from the given QUESTION, we get change in flux = 40 Wb.
