The core of a transformer is laminated because ratio of voltage in primary and secondary may be increased energy losses due to eddy currents may be minimised the weight of the transformer may be reduced rusting of the core may be prevented.

- C 8 f
- D f /2 2 _
Step-by-Step Verified Solution
We know that frequency of electrical oscillation in L.C. circuit is
f = 1 2 � 1 L C
_ f 1 f 2 = ( L 2 C 2 L 1 C 1 ) 1 / 2
= ( 2 L _ 4 C L _ C ) 1 / 2 = ( 8 ) 1 / 2
_ f 1 f 2 = 2 2
_ f 2 = f 1 2 2
_ f 2 = f 2 2 [As f 1 = f]
