![]() The bipolar transistor controls the current by varying the number of Silicon or germanium and come in two types. Transistors are active circuit elements and are typically made from Or modulating the flow of energy or power from an additional power The circuits we have encountered so far are passive and dissipateĮven a transformer that is capable of giving a voltage gain to aĪctive elements in a circuit increase the power by controlling ![]() Our product offerings include millions of PowerPoint templates, diagrams, animated 3D characters and more.Next: Bipolar Junction Transistors Up: PHYSICS LECTURE NOTES PHYS Previous: Problems is brought to you by CrystalGraphics, the award-winning developer and market-leading publisher of rich-media enhancement products for presentations.
