Given information
It is given in the question that
For a step down transformer to the home
Primary voltage,
Secondary voltage,
Step-by-step explanation
Step 1.
A Step Down Transformer is a device which converts high primary voltage to a low secondary voltage.
In a Step Down Transformer, the primary winding of a coil has more turns than the secondary winding
The transformer consists of two coils - primary coil and secondary coil.
Primary and secondary coils are input and output coils respectively
since Step down transformer, converts high voltage to low voltage , from the diagram it is clear that at the house, the voltage is changed from 7200 V to 240 V.
