A. Alternating Current (AC): An electric current that periodically reverses direction. Also referred to as AC.
B. Air Gap: A gap in an energized circuit that provides an isolation point.
C. Ammeter: An instrument used to measure current in an electrical circuit.
D. Circuit Breaker: A device that can be used to disconnect an electric circuit in order to prevent system damage.
E. Current: The flow of electricity that produces a charge in an electric circuit.
The use of electricity has vastly improved our lives, making things much simpler and faster. For example, us humans can benefit from the invention of alternating current (AC) powering our homes and businesses. In the simplest form, AC involves the transfer of electricity in a manner where it reverses direction within a cycle. This process of changing directions is known as a sine wave. Traditionally, electricity was transferred in a steady state manner, where the direction of electricity did not change, and was referred to as direct current (DC).
In order to use electricity safely, it is important to understand the components that make up a circuit. The air gap is a gap in an energized circuit providing an isolation point, in order to avoid any potential hazard from current flowing through it. This is often used in multiple devices where electricity must be distributed, but not connected directly, such as in a breaker panel.
An ammeter is an instrument used to measure current in an electrical circuit. It basically reads the amount of electricity that is flowing, enabling an individual to assess if a circuit is overloaded. Circuit breakers are also important in controlling how much current is allowed to flow. They basically act like a reset button that is used to disconnect an electric circuit and protect against system damage.
In order to accurately measure the electrical flow, one must understand that current is the flow of electricity that produces a charge in an electric circuit. This current is measured in amperes, and the resistance that could potentially slow it down is measured in ohms.
To help understand the basics of electricity, it is important to learn the fundamentals of electric circuits. The concepts of AC and DC, air gaps and ammeters, and breakers and current are all very important for the maintenance of any electrical system. Having a thorough knowledge of the components that make up a circuit and the dynamics of electricity makes it much easier to monitor and assess the safe use of electricity.
