Question

Two loops of wire are arranged so that a changing current inthe primary will induce a current in the secondary. The secondaryloop has twice as many turns as the primary loop. As long as thecurrent in the primary is steady at 3.0 A, the current in thesecondary will be Two loops of wire are arranged so that a changing current inthe primary will induce a current in the secondary.

Explanation / Answer

Given that The secondary loop has twice as many turns as the primary loop,that means Ns = 2Np Current in the primary coil is Ip = 3.0A Then the transformer ratio is         Is /Ip = Np / Ns          Is =(Np / Ns)Ip             = (1/2)(3.0A)             = 1.50A Therefore the current (Is) in the secondary coil = 1.50A
