Difference between a step up transformer and step down transformer are:
| Step up transformer | Step down transformer |
|---|---|
| It 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. |
