Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling […]

Is VBE always 0.7 V? What is V BE of a Transistor? VBE is the voltage that falls between the base and emitter of a bipolar junction transistor. VBE is approximately 0.7V for a silicon transistor. For a germanium transistor (which is more rare), VBE is approximately 0.3V. What is the principle of transistor? A […]
