What does AC mean in UNCLASSIFIED

What Is AC?

Alternating current (AC) is an electric current that regularly reverses its direction when alternating between positive and negative poles. This type of electricity is typically generated by sources such as hydroelectric power plants, and is often distributed through an electrical grid over long distances before it reaches its destination. While AC has some advantages over direct current (DC), like being able to transmit energy more efficiently over longer distances due to the alternating nature of the current, it also requires special equipment such as transformers to step down the voltage when used in homes or businesses.

What Is CE?

Common emitter (CE) circuits are used primarily as amplifiers or switches. They consist of three components — a base, collector, and emitter — which work together to control the flow of electrons from one part of an electrical circuit to another. A common emitter amplifier amplifies both voltage and current signals that enter through the base, while a common emitter switch can be used to turn an electrical device on and off by controlling the flow of electrons from one area to another.

How Do AC And CE Work Together?

AC and CE work together in order to ensure efficient transfer of electricity from one spot to another. The alternating nature of AC power makes it easier for electricity to travel over large distances without losing too much power along the way; however, in order for this power to be useable on a smaller scale — such as within a home or business — transformers need to be employed which then reduce the voltage so that it can safely be used within these locations without causing any damage or injury. Common emitter circuits are then employed afterwards so that these reduced voltages can then be amplified back up again in order for them to be usable within these areas accordingly.
