### More about Electrical system

Generators, batteries and external supplies can provide power in different conditions. Distribution arrangements connect that power to the required consumers.

An aircraft can have several circuits and backup sources. A fault in one part does not necessarily remove every electrical function, and its effect depends on the design and procedures.
