Symbols of Transmission Lines (Electrical Distribution)

The transmission lines and the electrical distribution systems form the set of structures and devices (transformers, cables, poles ...) responsible of transporting electricity from the source of generation to the final consumption centers.

Symbols of Transistors MOSFET and IGFET

Transistors of field effect (MOSFET and IGFET) are transistors constituted by a filament generally made of semiconductor silicon, called channel, and an associate diode called door. 
These symbols can be represented inside a circle.

Waveguides Symbols

A waveguide is a physical structure through which energy is transmitted in the form of electromagnetic waves. The modes of propagation depend on the wavelength, the polarization and the dimensions of the guide.

Transistor Symbols

The Transistor is a device semiconductor provided with three terminals called base, issuer and collector. It is used to work in electronic circuits as rectifier, amplifier, switch...
These symbols can be represented inside a circle.

Symbols of Electronic Sensors, Transducers, Detectors...

The transducers, sensors and electrical and electronic detectors are elements that are activated by the energy delivered by a system and that in turn deliver another type of energy to another different system. The transformed energy may be physical, chemical or biological origin.
