Why transformer is used?
A transformer used to step up or down the value of voltage.
What is the purpose of dc power?
theperpose of a power supply is to step up or step down an ac voltage to a desired dc value
What are transformers designed to operate with?
to step up voltage or to step down voltage
Device used to step voltage up or down?
As transformers do not work with DC., the answer is a voltage divider network (step down) or a voltage multiplier network (step up).
What is step up and step down?
Usually refers to a transformer. A step up transformer increases the voltage and a step down decreases the voltage by an amount proportional to the ratio of the windings between Primary and Secondary. A 1:2 ratio is a step up and doubles the voltage. A 2:1 would be a step down and halve the voltage.
Why transformer is used?

What is step voltage?
Step voltage is a type of AC voltage where the voltage signal represents a flat step up and then a flat step down.
What is the function of step-down transformers?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of Transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
What is the purpose of dc power?
theperpose of a power supply is to step up or step down an ac voltage to a desired dc value
What is transform function?
To stop up or step down the voltage
What are transformers designed to operate with?
to step up voltage or to step down voltage
When is a step up transformer used in relationship as to when a step down transformer is used?
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.

What equation is used to calculate the dc output voltage for a given ac input voltage to a step-down transformer?
so far i knew, the transformers are used to seprate dc component from ac component of supply fed into primary winding of coil. still if dc output value of ac input has to be calculated then it is v2*2/sqrt(pi) where v2 is peak ac output voltage and is equal to v1*n2/n1 pi is a constant numerically equal to 3.14 thus the dc value is average value of output ac voltage -------------------sachin_the_rex@aol.in------------------------------

Summary of the step-down transformer?
A step- down transformer is one whose secondary voltage is less than its primary voltage, it is used to reduce 'step down' the voltage applied to it. The number of coils in the primary circuit is greater that the secondary circuit. For instance, to step down 480 Voltage to 240 voltage, you need a step down transformer whose ratio of primary coils to secondary coils is 2:1.
What the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
