The parameters measured for a $220V$/$110V$, $50$ $Hz$, single-phase transformer are:

Self inductance of primary winding = $45$ $mH$
Self inductance of secondary winding = $30$ $mH$
Mutual inductance between primary and secondary windings = $20$ $mH$

Using the above parameters, the leakage ($L_{l1}$ , $L_{l2}$) and magnetizing ($L_m$) inductances as referred to primary side in the equivalent circuit respectively, are

1. $5mH$, $20mH$ and $40mH$
2. $5mH$, $80mH$ and $40mH$
3. $25mH$, $10mH$ and $20mH$
4. $45mH$, $30mH$ and $20mH$
