Question 12 of 15 1 Points Point(s) deducted for incorrect answer: 0.5 If Coil 1 is energised to produce a self-inductance of L, doubling the number of tums in Coil 1 would produce a self-inductance of 2L True False Reset Selection Part 11 of 13 - Inductance cont Question 13 of 15 1 Points Point(s) deducted for incorrect answer: 0.5 If Ny is half of N, Self-inductance of Coil 1 is L, the mutual inductance L71 i U2 True False Reset Selection Part 12 of 13 - Inductance cont... Question 14 of 15 1 Points Points) deducted for incorrect answer 05 Increasing the cross-sectional area of the core will decrease the self-inductance, True False

Answer 1

The self inductance of a cail is gran by L = NZUA । No no. of turns Az Area of coil l Average length of cail M = Permeability of core 12 as N lucones double L's (21) MA I L'= 4N²UA I L'z 4L so Inductance livcome times so it is false

13 given by Mutual Inductance L212 NN, MA T If Nzz M L2i = NZUA 2 4 = N²uA of coil I 2 d So Lai 2 1 2 4 / 4 So this statement is true

14 as La N²uA d as Gross section area phcreased АТ Soff inductance increase So this statement is False

Gehen we add an air (15) The Self inductance La Nd where &z Plusc gap it increases the reluctance of path as Reluctance Rze total Re Rg the all Rge gap Relactance Rcz Pore Reluctance o decrease so L decreases hence this statement is false as & 2 NI R
