WebA transistor used as a switch (in saturation) will typically have a collector-emitter voltage of about 0.2 volts. Since the base-emitter voltage will be about 0.7 volts, Vs must be at least 0.5 volts above Vcc, plus whatever voltage is required across R2 to get the base current up to the level required. And that base current will be significant. WebMar 19, 2024 · Because a transistor’s collector current is proportionally limited by its base current, it can be used as a sort of current-controlled switch. A relatively small flow of electrons sent through the base of the transistor has the ability to exert control over a much larger flow of electrons through the collector.

WebSep 7, 2024 · The transistor contains a maximum allowed current that is able to restrict the amount of current as it passes from terminal to terminal. Depending on the order of the terminals in the transistor, the transistor will act as either a conductor or an insulator when in the presence of a controlled current. WebGenerally no arrow head is marked for collector since its reverse leakage current is always opposite to the direction of emitter current. 4. Discuss the need for biasing the transistor. For normal operation, base-emitter junction should be forward biased and the collector-base junction reverse biased. green sheers for living room
