1 Definition

Electricity: It's the science that studies the movement of the electrons.

 The electrons have energy. Electricity is a form of energy that moves quickly. It's a very useful way to transport energy far from its origin. (From power station to the city).

                Electronic: It's a branch of technology that studies the uses of electricity to transmit information.

Electrical circuit: It’s the path where the electrons move to change the kind of energy.

Current: is the movement of electrons along a conductor. The electrons jump from one atom to another. When there are more atoms moving the current is more intense.

Electric tension difference

Electric tension is the difference in electrical potential between two points

Fundamental Electrical Signal Parameters

• Cycle: A part of the signal that is repeated.
• Period (T): The time, measured in seconds, that one cycle lasts.
• Frequency (f): The number of cycles repeated per second (Hertz).
• Instantaneous Value: The value of the signal at any given moment.
• Maximum Value (V_max): The greatest signal value within a period (Peak Value).
• Minimum Value (V_min): The smallest signal value within a period (Trough Value).
• Effective Value (V_eff or RMS): The value of an equivalent continuous current that produces the same electrical work. V_eff = V_max / √2

Active and Passive Electronic Components

Active Components

These components are able to generate, modify, or amplify an electrical signal.

Passive Components

Acting as loads, these components... Continue reading "AC Signal Parameters and Core Electronic Components" »
