<h2>What does a car alternator do?</h2>
The alternator keeps your automobile alive when the engine is running, however, the battery is necessary to start your car when it is not functioning. The majority of your car's electronic parts, such as the headlights, electric steering, power windows, windshield wipers, heated seats, dashboard gauges, and radio, are powered by the alternator while you're moving or idle. All of them receive direct current (DC) electricity from the alternator. Your car's battery is also charged while you're driving thanks to your alternator. 
By converting mechanical energy into electrical energy, the alternator operates. When your engine is running, it drives a drive belt that is suspended from an alternator pulley. A set of magnets is spun around a coil by the alternator's rotor shaft, which is turned by the pulley. Alternating current (AC) is produced by these rotating magnets and circulated through the coil to the rectifier of the alternator. Your car's electrical systems are turned on by the rectifier, which transforms that AC power into DC power.
<h2>How does a car alternator work?</h2>
A car alternator is a device that converts mechanical energy into electrical energy. It is responsible for charging the battery and powering the electrical systems of the car. When the engine is running, the alternator is driven by a belt connected to the engine's crankshaft. Inside the alternator, there is a stationary magnetic field and a rotating coil of wire called the rotor. As the rotor spins, it generates an alternating current (AC) by electromagnetic induction.
The output of the alternator is regulated by a voltage regulator, which maintains a constant voltage output even as the engine speed varies. When the battery is fully charged, the voltage regulator reduces the output of the alternator to prevent overcharging the battery. When the engine is idling, the alternator output may not be enough to power all of the car's electrical systems, so the battery may be used to provide additional power. When the engine is running at higher speeds, the alternator output increases to meet the demand for electrical power.
<h2>Symptoms of alternator failure</h2>

<li>Battery warning light on the dash</li>
<li>Dim or overly bright lights</li>
<li>Growling or whining noises</li>
<li>The smell of burning rubber or wires</li>
<li>Dead battery</li>
<li>Slow or malfunctioning accessories&nbsp;</li>
