Question

A step down transformer steps up ................... and steps down .................

Answer 1

Current, Voltage

Step down transformer steps down the voltage from higher value to a lower value and steps up current from lower value to higher value so as to make product of voltage and current as constant on both the sides of transformer.

$\frac{V_1}{V_2}=\frac{I_2}{I_1}=constant$

$V_1{I}_1=V_2{I}_2=constant$
