Transformers Interview Questions & Answers ... is transformer flux constant? When a load is connected to a transformer current (say I 2) flows through secondary coil thus an M.M.F (N 2 I 2) is produced, this produces the secondary flux.This flux reduces the main flux induced in the primary & also reduces E.M.F E 1 in the primary. As a result more current is drawn from the supply.
