A standard alternator that has a self fully self-contained unit and one thing to remember. When we’re dealing with alternators the essentially what you have is an AC output. But in order to get an AC output. We have to be able to generate some sort of DC current inside to provide a field. That’s done using essentially a DC generator.
We’re looking at a self-contained unit and you can see what we essentially have is the DC generator. And if you recall back to when you took generators. We have a field and we have an armature and it’s that exciter field that provides the Residual magnetism with the north and a south pole.
Both Alternating Current and Direct Current describes the two types of current flow in a circuit. In direct current, the electric charge or current flows in one direction. In alternating current, the electric charge changes direction periodically. The voltage in AC circuits also sometimes reverses because of the current change direction. Most of the digital electronics that you build by using DC. However, it is easy to understand some AC concepts. Most houses are wired for AC, so if your idea to connect your Tardis melody box project to an outlet, you will need to convert AC to DC. AC also has some useful properties, such as being able to convert the voltage levels with a single component like a transformer, which is why initially we have to choose AC means to transmit electricity over long distances.
Generators and alternators are the primary methods of producing electric power. Generators create direct current (DC) power and alternators create alternating current (AC). In the early days of automobiles, cars had DC generators; these have been completely replaced by alternators in modern vehicles. Likewise, in the early days of commercial power generation, a battle ensued between the technical wizards of the day between DC and AC maintenance -- a battle that AC won. But while alternators have been the big winners, generators still have their uses.
DC alternators (like generators) change mechanical energy into electrical energy by the process of electromagnetic induction. In general, DC alternators are lighter and more efficient than DC generators. DC alternators and their related controls are found on modern, light, piston-engine aircraft. The alternator is mounted in the engine compartment driven by a v-belt, or drive gear mechanism, which receives power from the aircraft engine. [Figure 9-64] The control system of a DC alternator is used to automatically regulate alternator output power and ensure the correct system voltage for various flight parameters.
DC alternators contain two major components: the armature winding and the field winding. The field winding (which produces a magnetic field) rotates inside the armature and, using the process of electromagnetic induction, the armature produces a voltage. This voltage produced by the armature is fed to the aircraft electrical bus and produces a current to power the electrical loads. Figure 9-65 shows a basic diagram of a typical alternator.

Ever heard of Car maintenance, AC maintenance, House Maintenance, etc.
Every living and nonliving thing requires some kind of maintenance.
Why do we tend to ignore the most precious living thing – our Body and don't think of Body Maintenance?
Why is the message ‘excel not working’ displayed?The error message ‘excel not responding’ is usually displayed due to the following reasons.
When you have not installed the latest Excel application or the updatesYour Excel application may be used by another processPre-installed add-ins may be interfering with your Excel application, thereby preventing it from working properlyThere could be some issue with your MS Office programOutdated antivirus software could sometimes be the issueEffective ways for fixing the ‘Excel not working issueHere is a set of comprehensive solutions you can try to fix the ‘Excel not working issue.Install the latest version of Microsoft OfficeIf you have not upgraded to the latest Office and Windows Updates, then the error message can show up.
You can do this following this simple step.Control Panel>System and Maintenance>Maintenance>Automatic MaintenanceSave the Excel file in Safe ModeFor resolving the issue, you can open the Excel file in Safe Mode.
When you run the Excel file in safe mode, it bypasses all the settings and functionality such as add-ins, changed toolbars, and alternative startup locations.
You can open the file in safe mode by pressing and holding the Ctrl button while you start the program.
You can also do it by using the safety switch in Command Prompt.Make sure the excel file is not in use by another processIf an Excel file is in use by another process, then you could sometimes be displayed an ‘Excel not working’ message.
