  2. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

  5. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.

  6. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

  7. Unijunction transistor - Wikipedia

    en.wikipedia.org/wiki/Unijunction_transistor

    The schematic diagram symbol for a unijunction transistor represents the emitter lead with an arrow, showing the direction of conventional current when the emitter-base junction is conducting a current. A complementary UJT uses a p-type base and an n-type emitter, and operates the same as the n-type base device but with all voltage polarities ...

  8. Floating-gate MOSFET - Wikipedia

    en.wikipedia.org/wiki/Floating-gate_MOSFET

    The floating-gate MOSFET (FGMOS), also known as a floating-gate MOS transistor or floating-gate transistor, is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) where the gate is electrically isolated, creating a floating node in direct current, and a number of secondary gates or inputs are deposited above the floating ...

  9. 555 timer IC - Wikipedia

    en.wikipedia.org/wiki/555_timer_IC

    For the schematic on the right, a Reset input signal connects to the RESET pin and connecting a Set input signal to the TR pin. Thus, pulling Set momentarily low acts as a "set" and transitions the output to the high state (V CC). Conversely, pulling Reset momentarily low acts as a "reset" and transitions the Out pin to the low state (GND).
