What is excitation of a DC motor?
DC Voltage
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.
Is DC voltage and average voltage same?
no, dc volatage is a type of current direct current, ac is alternating current, average voltage could be any type of voltage ac or dc that maintains a constant rangeAnswerNo. A DC voltage is exactly equivalent to an AC rms-voltage. So, for example, 100 V (DC) is exactly equivalent to 100 V (AC rms). The average value of an AC waveform is zero.
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 is the output voltage of megger is it ac or DC?
megger are available in ac &dc
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 value of voltage measure by DMM Vrms or Dc voltage?
Many can measure both - Vrms (AC) or 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.
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.
Can a fan work on a DC voltage?
Yes, if the fan is designed to work on DC voltage, otherwise no.
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.
What is a dc to dc converter?
converting dc current to dc in different voltage rating
