DC Voltage is kind of like water pressure. It needs a conductor (usually a wire) in order to travel. The same way you need a garden hose to carry water pressure. Voltage will drop due to resistance in a very long conductor if a significant current is being drawn.

How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
What value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or DC voltage.
What device used to increase or decrease DC voltage?
A DC-to-DC converter is the general term for a device that changes DC voltage at one level to another.
Why is DC is not use in home?
because in dc current is direct current and it continously varies. so it may be possible that some instrument may be damaged. so to avoid this first we have to convert dc to ac. Actually in our home dc is provided.suppose you want to charge your mobile than you have to convert first dc current to ac current.AnswerAll homes are supplied with AC voltage. The reason for this is that the magnitude of an AC voltage is easily changed using a transformer, and it is easily changed into DC using a rectifier. Changing the voltage level of DC is far more complicated, as is changing it to AC.
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
Why is there a difference between dc pass through and bidirectional with coaxial splitters?
A DC pass through will pass a DC voltage in only one direction. Bidirectional will let a DC voltage travel both directions.
What direction does dc Voltage travel in?
It travels from negative to positive. The opposite of what you might think.
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
What is meant by DC-DC luo converter?
luo converter is a new technique adopted for dc to dc voltage lifting(dc voltage boosting)...
How is DC voltage represented on multimeters?
DC
What is excitation of a DC motor?
DC Voltage
What is commutation in DC machines?
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
What value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or DC voltage.
What voltage is DC?
A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.
Do batteries provide a DC voltage or an AC voltage?
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
Why smps convert ac to dc and again to dc to dc?
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
