Bright Tutorials · Accepted Answer

Difference between a step up transformer and step down transformer are:Step up transformerStep down transformerIt increases the a.c. voltage and decreases the current. i.e., Es > Ep and Is < Ip.It decreases the a.c. voltage and increases the current i.e., Es < Ep and Is > Ip.The wire in the primary coil is thicker than that of the secondary coil.The wire of the secondary coil is thicker than the primary coil.

Step up transformer	Step down transformer
It increases the a.c. voltage and decreases the current. i.e., E_s > E_p and I_s < I_p.	It decreases the a.c. voltage and increases the current i.e., E_s < E_p and I_s > I_p.
The wire in the primary coil is thicker than that of the secondary coil.	The wire of the secondary coil is thicker than the primary coil.
