NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.
Turn the DC generator inside out and you have an alternator .
megger are available in ac &dc
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.
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
the sum of the two

AC !
The major difference between an AC generator and a DC generatoris that the DC generator requires a mechanism to provide a DC output. This can be done mechanically with a commutator or electronically with a rectifier. Internally, all generators produce an alternating voltage. Allgeneratorsrequire a magnetic field.
No, you cannot accurately measure the output voltage of an Automatic Voltage Regulator (AVR) using a DC meter, as the AVR typically regulates AC voltage for the generator. A DC meter is designed for measuring direct current voltage, while the voltage output from a generator is usually alternating current (AC). To measure the AC voltage effectively, you would need an AC voltmeter or a multimeter set to the AC voltage setting.
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.
either a rectifier or a motor generator
dc
It may not be possible to physically convert AC generator to DC generator. What can be done is that 'Rectifier' of suitable capacity can be connected to the out put of AC generator to get DC supply.
current flows in both directions, depending on the AC voltage, i.e when ac is higher, current flows to the dc side, and vice versa
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
It should produce 14.5v +/- and it's DC.
U sohuld replace the slip-ring which it is in the AC generator to a commutator. It is a split-ring. Then u can produce DC generator.
