In reverse bias the ideal diode is similar to an open switch with current equal to zero and infinite ( ∞ Ω ) resistance. The schematic symbol used for the diode is typically an arrow with a short line ...

When looking across the discrete components in your electronic armory, it is easy to overlook the humble diode. After all, one can be forgiven for the conclusion that the everyday version of ...

You will learn about semiconductor light-emitting diodes (LEDs) and lasers, and the important rules for their analysis, planning, design, and implementation. You will also apply your knowledge through ...

JK Rowling has revealed the inspiration behind the symbol for the Deathly Hallows. Speaking in a new BBC documentary, the author says it's connected to a film that came out more than 40 years ago.

The filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it and produces light as a result.

Symbols show important landmarks, places and areas. They are used because maps are usually too small to contain lots of writing A key is a guide which explains what the symbols on the map mean. It ...

For as many keys as your keyboard holds, there are always hundreds more symbols that get left out. One of these is the degree symbol. Luckily, the degree symbol is on your keyboard - just hidden ...

Despite its misleading electrical symbol, think of the TL431 as being ... the TL431 does behave like a zener diode that has a breakdown voltage of 2.5 V, but that’s selling it short.

Incoming PNG representative coaches Tahnee Norris and Jason Demetriou have named their representative sides in their new roles, selecting their squads for the upcoming Prime Minister’s XIII ...

Australia has committed up to $600 million over a decade to bolster PNG's pitch to secure a team in the competition, with the NRL set to make a final decision in coming weeks. But the ABC revealed ...

Varactor diodes are two-terminal electronic components that are designed to provide voltage-controlled capacitance when operated under reverse bias. These simple semiconductors are PN junctions with a ...
