This means direct current.
There is only 1 type of DC voltage, and that is direct current. In order to better answer your question, you need to be more specific.
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?
luo converter is a new technique adopted for dc to dc voltage lifting(dc voltage boosting)...
"The application of a DC voltage in forward bias mode to a circuit containing a diode will result in a specific DC voltage and DC current across the diode, known as the DC operating point, Q point (VDQ, IDQ)." source: http://www.doe.carleton.ca/~achar/notes_2507/Lab3_tutorial_diodes.pdf
You don't. The solenoid's voltage rating means that it needs that much voltage to operate correctly.
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.
DC Voltage
DC
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.
Many can measure both - Vrms (AC) or DC voltage.
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.
