The formatting of the question can be redone.
The primary coil of a step-down transformer has more number of turns.
A transformer consists of three basic parts, as shown in figure. These are an iron core which provides a circuit of low reluctance for magnetic lines of force, a primary winding which receives the electrical energy from the source of applied voltage, and a secondary winding which receives electrical energy by induction from the primary coil. The primary and secondary of this closed core transformer are wound on a closed core to obtain maximum inductive effect between the two coils.
On a step-down transformer there are more turns on the primary coil than the secondary coil. The induced voltage across the primary coil is greater than the applied voltage across the secondary coil or in other words the voltage has been stepped-down".
