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.

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. WebIn almost any transistors, less than 5 % of emitter current flows which indicates that the value of β is generally greater than 20 and its range lies between 20 to 500. We generally use this type of configuration because it gives tangible voltage gain and current gain. Relation between β and α: A Simple relation is established between β and α.

WebTransistors are manufactured in different shapes but they have three leads (legs). The BASE - which is the lead responsible for activating the transistor.
