1.	As the number of turns in the coil increases, what happens to the inductance of the coil?(a) Increases(b) Decreases(c) Remains the same(d) Becomes zeroThis question was addressed to me during an internship interview.I need to ask this question from Factors Determining the Inductance of a Coil topic in section Inductance in a DC Circuit of Basic Electrical Engineering
Answer» RIGHT choice is (a) Increases The BEST explanation: Inductance is directly proportional to the SQUARE of the NUMBER of turns in the coil, HENCE as the number of turns increases, inductance also increases.
