The voltage induced at the end of primary terminals of a two winding transformer consisting of N turns is?
(a) -N*dϕ/dt
(b) N*dϕ/dt
(c) -dϕ/dt
(d) -N*dt/dϕ
This question was posed to me in an interview for internship.
Asked question is from Ideal Two Winding Transformer topic in chapter Transformers of Electrical Machines
