What is 2N5551?

A well-known NPN bipolar junction transistor (BJT) is the 2N5551. They are renowned for their exceptional performance in a range of electrical applications and their high voltage capabilities. When enough voltage is supplied to the base of the 2N5551 transistor, which is an NPN transistor, it may conduct current because it is made up of two layers of N-type material layered on top of a single layer of P-type material. The circuits of amplifiers frequently use this transistor. Changing between programs and standard electronic devices due to its strong features The 2N5551 is perfect for high voltage applications because it has a maximum emitter-to-emitter voltage (Vce) of 160V and a collector current (Ic) of 600mA. It is therefore a crucial part of many different kinds of electronic designs.

What is Junction Field-Effect Transistor (JFET)?

Do you know Junction Field-Effect Transistor (JFET) ?
A Junction Field-Effect Transistor (JFET) is a type of field-effect transistor that is widely used in electronic circuits. It operates by using an electric field to control the flow of current. Here are some key points about JFETs:

Protocol based url reading inside electorn

Can any one help me on this. I have an electorn application, and i have created the custom protocol named essc. From any browser(chrome,firefox, etc) if i browser like essc://www.electronjs.org/. That url need to open electron application first and remaining part of (URL www.electronjs.org/) need to bind in electron browser frame. Can this be achieved?

Bonjour j’essaie de d’executer le build de mon app electron et react mais j’aobtien cette erreur pouvez vous m’aider c’est urgent svp
