Cut off (no collector current), useful for switch operation. ... Transistor load line ... The base-emitter voltage can be considered to be the controlling variable in determining transistor action. The collector current is related to this voltage by the Ebers-Moll relationship (sometimes labeled the Shockley equation):

Part of the manufacturer's data for transistors is a set of maximum values which must not be exceeded in its operation. These form some of the constraints on transistor operation which are a part of the design of any circuit.

The PNP transistor works essentially the same as the NPN transistor. However, since the emitter, base, and collector in the PNP transistor are made of materials that are different from those used in the NPN transistor, ... Figure 2-11. - PNP transistor operation. ...

But if you DO manage to decode my explanations and crude ASCII artwork, I think you'll be in the elite minority who really understands transistors. I've found that even most working engineers have no good mental picture of bipolar transistor operation.

Two Transistor (Boy's Radio) Schematic and Theory of Operatio ... The second transistor acts as a power amplifier, with the output signal going through an audio output transformer (to provide impedance matching again), and then finally to the speaker. Everything about this circuit is designed to provide maximimum gain;

How does a transistor operate and what can it do ... The transistor has many applications, but only two basic functions: switching and modulation -- the latter often used to achieve amplification. In the simplest sense, the transistor works like the dimmer in your living room.

Bipolar Junction Transistor Operation and Biasing ; Summary ... Several voltages are normally involved in any discussion on transistor operation. (See Figure 19.3 and Table 19.1.) VCC, VEE, and VBB are used to identify dc power supply (biasing) voltages. VC, VE, and VB are all voltages measured from their respective...

How does a transistor work? Asked by: Tony Whelan ; Answer; The design of a transistor allows it to function as an amplifier or a switch. This is accomplished by using a small amount of electricity to control a gate on a much larger supply of electricity, much like turning a valve to control a supply of water.
