Difference between step-up transformer and step-down transformer

S.NO.	STEP-UP TRANSFORMER	STEP-DOWN TRANSFORMER
1.	The primary and secondary winding turns ratio of a step-up transformer is greater than 1.	It is less than 1 for a step-down transformer.
2.	A step-up transformer increases the voltage of an AC signal.	A step-down transformer reduces the voltage.
3.	A step-up transformer has a higher primary winding current and a lower secondary winding current.	A step-down transformer has a lower primary winding current and a higher secondary winding current.
4.	The power output of a step-up transformer is greater than its input power.	A step-down transformer has a lower output power than its input power.
5.	A step-up transformer is typically larger and heavier.	A step-down transformer of the same power rating is smaller and lighter.
6.	A step-up transformers being commonly used in power transmission systems.	A step-down transformers being used in power distribution systems.
