An alternator does not need a gauge to work. It is used to monitor the output of the alternator.
A dynamo is different than an alternator in the fact that the rotor is a fixed magnet rather than an electro magnet as used in an alternator. This makes a dynamo a constant output device. Usually the output is connected to a relay that opens when the battery is fully charged and the current is wasted. the only way increase output is to rewind the stator with more coils of wire. It is usually not possible to fit any more wire in the iron core of the stator as they are designed to be full at the designed output current rating.
To measure amperage output to see if an alternator is charging or not .
The devices that develop electric power are a generator (for direct current), or an alternator (alternating current). In a car, an alternator is used, with a rectifier, because of size and weight considerations.
Automobile alternator is used to supply the A.C current to the vehicles but the vehicles need D.C current so there is an diodes and rectifier to convert the A.C current into D.C current Automobile alternator is used to supply the A.C current to the vehicles but the vehicles need D.C current so there is an diodes and rectifier to convert the A.C current into D.C current Automobile alternator is used to supply the A.C current to the vehicles but the vehicles need D.C current so there is an diodes and rectifier to convert the A.C current into D.C current Automobile alternator is used to supply the A.C current to the vehicles but the vehicles need D.C current so there is an diodes and rectifier to convert the A.C current into D.C current Automobile alternator is used to supply the A.C current to the vehicles but the vehicles need D.C current so there is an diodes and rectifier to convert the A.C current into D.C current
alternator can produce the current to supply in the vehicle our vehicle needs D.C current but the alternator can produce A.C current the A.C currrent can convert into D. current by diodes ADVANTAGES OF ALTERNATOR: it is light weight it is compaq in olden days generator are used but it is a heavy weight and it can occupy more space so alternators re used

The Current in a automobile is DC, you have a battery which is dc, and your alternator produces ac current but converts it to DC inside the alternator unit which gives your battery DC power. So basically everything in your car is DC.
An alternator produces direct current that is used to charge up the battery while the car is running.
When a generator is connected to a load it is never going to be perfectly matched because of its inductance, when you have inductance the current starts to lag.
The only type of current used by automobiles is dc current although the alternator produces ac current which is converted to dc by rectifiers built into the alternator. Even the alternator is controlled by dc current though through the use of a voltage regulator which limits the amount of negative dc sent to the stator and positive dc current sent to the rotor of the alternator which limits the EMF.
Resistors are used to control current flow.
