This voltage should increase as you continue to increase the supply past 1.8 Volts.
As this happens, current is driven through the collector resistor, so a voltage should appear across this resistor. As the voltage supply approaches 1.8 Volts, the transistor should start to turn on. The base-emitter voltage of the 2N3055 is about 1.8 Volts. the transistor are base, emitter and collector and it is essential that each leg. Gradually increase the voltage supply that is connected to the base resistor, and watch the reading on the voltmeter. The base of the transistor must always be connected via a protective. The voltage should be zero volts, because with no base voltage, the transistor is turned off, so no current is passing through the resistor. Touch the probes of the voltmeter to the leads of the collector resistor. Set the collector voltage supply to 10 Volts and the base supply to 0 Volts. The emitter and collector were made by diffusing two pellets of Indium (a trivalent. Insert a wire that connects the emitter of the transistor to the ground rail. Typically a thin wafer of Germanium was used for the base of the transistor.
It was introduced in the early 1960s by RCA using a hometaxial power. CER Collector-emitter sustaining voltage I C0.2A R BE100 70 V V CEsat-1 Collector-emitter saturation voltage I C4A I B0.4A 1.1 V V CEsat-2 Collector-emitter saturation voltage I C10A I B3.3A 3.0 V V BE Base-emitter on voltage I C4A V CE4V 1.5 V I CEO Collector cut-off current V CE30V I B0 0. Connect the negative terminals of the supply voltages to one of the long "bus" strips on the breadboard (these usually run horizontally at the top and bottom of the breadboard). The 2N3055 is a silicon NPN power transistor intended for general purpose applications.Connect one positive supply voltage to the unconnected lead of the base resistor, and connect the other positive supply voltage to the unconnected lead of the collector resistor.
