Q. Which is better, an ammeter or a voltmeter?

Answer

According to Hamilton, an alternator has a far higher cooling capacity and can work much harder for longer because of its hefty fixed stator windings. Electrical pressure is measured by a voltmeter, while current is measured by an ammeter. Due to their low-duty cycle, conventional generators could not handle the stress of constantly charging batteries for lengthy periods of time. The brushes of a generator pick up electricity from the armature terminal and transmit it to the rest of the machine via segments of the commutator that are soldered to the armature. At shutdown, the old generator system's regulator would eliminate power to the generator and the batteries by means of a cut-out relay and a current limiter.
