The primary and secondary winding of a transformer are _____ coupled.

Answer: B. Magnetically

The primary and secondary winding of a transformer are electrically separated but magnetically connected through a common magnetic core.

Solution

Transformer is an electrostatic device, which consists of two are more electric circuits (or) windings, these windings are separated electrically but interlinked magnetically by a common magnetic core. Transformer is used to transfer electrical energy from one alternating-current circuit to another through the common magnetic core at the same frequency.

So, the primary and secondary winding of a transformer are magnetically coupled.
