A $60\;w$ load is connected to the secondary of a transformer whose primary draws line voltage. If a current of $0.54\;A$ flows in the load, what is the current in the primary coil ? Comment on the type of transformer bring used ?

Question

$\begin{array}{1 1} I_p= 2.7\;A \;Step\;up\;transformer\\ I_p= 0.27\;A \;Step\;down\;transformer \\ I_p= 27\;A \;Step\;down\;transformer \\ I_p= 2.7\;A \;Step\;up\;transformer\end{array} $
