Transformer works on the principle that,
I1V1 = I2V2 at all times.
where I1V1 are primary current and voltage respectively;
,, I2V2 are the corresponding secondary current and
voltage respectively. From the above equation, if you step-
down the voltage the current must increase to maintain the
equality and vice versa. Based on this principle, the
makers of transformers ensure that the gauge of copper
wire used in the LV-winding can withstand the current
together with tolerance.
