There are three leads on each transistor. Transistors regulate and control the voltage between two leads to control the flow of current.

These are unique in that they allow you to control the flow of current through the circuit. Electrical signals such as current and voltage are regulated, methodized, and amplified by it. Our product offerings include millions of PowerPoint templates, diagrams, animated 3D characters and more.A transistor is a semiconductor that exchanges or transfers a weak signal from a sink resistance circuit to a source resistance circuit. is brought to you by CrystalGraphics, the award-winning developer and market-leading publisher of rich-media enhancement products for presentations. Then you can share it with your target audience as well as ’s millions of monthly visitors. We’ll convert it to an HTML5 slideshow that includes all the media types you’ve already added: audio, video, music, pictures, animations and transition effects.

You might even have a presentation you’d like to share with others. And, best of all, it is completely free and easy to use. Whatever your area of interest, here you’ll be able to find and view presentations you’ll love and possibly download. It has millions of presentations already uploaded and available with 1,000s more being uploaded by its users every day. is a leading presentation sharing website.
