I reckon this is mostly found in a wire connected to the picture tube of your TV. A flashligh battery is 1.5 volts. The DC on your pic tube may be 25 thousands volts or more. Also, the term HVDC is a method of utility power transmission where buried cables use very high voltage DC instead of the usual AC to supply power over long distances. See the related question.

What is hvdc power transmission?
'HVDC' stands for high-voltage, direct current.
What is the voltage of French national grid?
The voltage of the French National Grid is 2000 mw high voltage. It is a direct current electrical interconnector between the British and French transmission.
When voltage is reduced 75 percent current is reduced?
This statement is correct.
What is the meaning of DC Voltage?
D.C. stands for direct current. A.C. is alternating current.
What is the Difference Between VAC and DC Current?
VAC is voltage of alternating current signalDC current is amperage of a direct current signalAnswerYour question contradicts itself, as the symbol, V,represents voltage, not current.However, V a.c., represents an alternating voltage -one in which the direction in which the voltage is acting continuously reverses itself. Vd.c. represents a direct voltage, in which the voltage continuously acts in the same direction.
What type of current only consists of direct current at a low voltage and high amperage?
battery
What is hvdc power transmission?
'HVDC' stands for high-voltage, direct current.
What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
Whether high impedance drives the currecnt or voltage more?
No, This will act in reverse.Note: This will act only for alternating current and there will be no effect on direct current.
What is the voltage of French national grid?
The voltage of the French National Grid is 2000 mw high voltage. It is a direct current electrical interconnector between the British and French transmission.
What type of electrical current does a notebook require and what device provides this current?
A notebook computer generally requires direct current. This current comes from a battery or a power supply. A battery converts chemicals into electricity, while a power supply or battery charger converts somewhat high voltage alternating current into lower voltage direct current.
In electric terms what do the abbreviations AC and DC mean?
Its Alternate Current and Direct Current. I believe Angus Young got the idea for the band name when he say AC/DC on the bottom of his sisters sewing kit. Electric current can be direct current (DC) or alternating current (AC). Direct current such as the power from dry cells is characterized by a uniform direction of flow and amount (voltage) of electricity.
What are the kinds of voltage?
Alternating current - AC, and direct current - DC.
How does ac dc power supplies work?
The mains to the house is an alternating current and this high voltage is stepped down using a transformer. The low voltage secondary alternating current is converted to direct current using 4 diodes wired as a bridge rectifier. The 'lumpy' direct current is smoothed using an electrolytic capacitor to smooth the resulting dc. It may need to be voltage regulated if the circuits it feeds are voltage sensitive.
How can you interconnect two generating station operationg at 60Hz and 50Hz?
Through the use of a high-voltage direct-current link.
When voltage is reduced 75 percent current is reduced?
This statement is correct.
What is DC in voltage means?
This means direct current.
