  6. Junction temperature - Wikipedia

    en.wikipedia.org/wiki/Junction_temperature

    For example, a typical white LED output declines 20% for a 50 °C rise in junction temperature. Because of this temperature sensitivity, LED measurement standards, like IESNA ’s LM-85 Archived 2017-10-18 at the Wayback Machine , require that the junction temperature is determined when making photometric measurements.

    Fig. 1: Schematic of a buck–boost converter. Fig. 2: The two operating states of a buck–boost converter: When the switch is turned on, the input voltage source supplies current to the inductor, and the capacitor supplies current to the resistor (output load).

  8. Electronic color code - Wikipedia

    en.wikipedia.org/wiki/Electronic_color_code

    A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.

  9. Goto - Wikipedia

    en.wikipedia.org/wiki/Goto

    "GOTO" key on the 1982 ZX Spectrum home computer, implemented with native BASIC (one-key command entry).. Goto is a statement found in many computer programming languages.It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control.
