Connect a variable resistance across DC source (fixed ends of variable resistor or Rheostat) and take decreased DC output across its one fixed terminal and other variable terminal of variable resistor.
Other method is connect variable resistor in series with DC output and load, vary the resistance and take decreased DC voltage as required.

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.
In a circuit where is the voltage drop?
In a circuit, the voltage drop is located wherever there is resistance. Ohm's law: voltage = resistance * current; so without resistance there can be no voltage drop, with resistance there is.
How can you convert 1000000 volts to several hundred 9 volt power sources?
On the whole AC electrical conversions are done with transformers. In your question both step up and step down transformers will be utilized. Step up transformers will be utilized to get the generated voltage up to transmission voltage. At the voltage transmission destination the voltage will use step down transformers to decrease the voltage to the consumers load requirement. Or you could connect 111111 resistors in series and take the voltage off each one of them .. but ull have to put in consideration the load resistance ..
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 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.

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
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
How do calculate secondary current of step down transformer?
The secondary current is determined by the load. So, divide the secondary voltage by the load impedance.
