bipolar junction transistor amplifier
I need help with this problem biopol junction transistor?
1 – When a transistor circuit is checked out, a very low resistance reading should be obtained between the C and E, leads a good transistor? True or False 2 – tranistor An amplifier has an input voltage of 76mV and an output voltage of 2.48 V. The voltage gain is what? 3 – In an NPN transistor most carriers in the base are holes or free electrons or both? 4-In a bipolar junction transistor, collector current is controlled by a collector voltage of the base current BC-resistance collector or for all? 5 – When a transistor switch is in the mainstream the collector current is limited by the base-b-c-colloctor resistance base voltage or resistance d-base?
1. False – should read 2 high. Gain = 2.48 / 0.076 (you can do in the calculator division) 3. holes – the base of a NPN is' P ', which has holes (' P'ositive charges) as the bearer of the majority. 4. b. base current – which is a fundamental characteristic of BJT 5. b. collector resistance – when a transistor switch is that is known as saturation. The tension between the collector and emitter is very low (less than 1 / 2 volts). It acts as an amplifier, and the only current limiting flowing through it is the internal collector resistance ..
