Transformer

(1/2) > >>

Andy56:
A transformer has a primary winding of 10 turns and a secondary winding of 100 turns. On the secondary side, the transformer is loaded with an ohmic resistance of 1.2 kohm. To what size is this transformed on the primary side?

Benta:
This is not really a free "we do your homework for you" page.

Andy56:
Pls help me with this.

ArthurDent:
Think ratio

TimFox:
Apply the turns ratio separately (in the appropriate direction) to the voltage and current.  Past that is homework left to the student.
