The primary coil of a transformer has 2000 turns and secondary coil is connect to a 240V a.c. mains supply.
(a)Explain how an e.m.f. is induced in the secondary voltage.
(b)Determine the secondary voltage

joseph
a. The changing current in the primary coil induces a current in the secondary coil due to changing magnetic field of the primary current.
b. Vs/Vp = Ns/Np
Vs =( 400 x 240)/2000
= 48 V
