WebJan 6, 2024 · It acts as a Voltage switch that limits current. 0.6V/47 ohms = 12mA err 12.77 actually up to 15mA at cold temp as 0.6 rises 4mV/'C to 0.7V at +25'C rise 0.7/47=15mA which is a typical BJT Op Amp current … WebTransistor as a Switch. A transistor can be used as a solid-state switch. If the transistor is operated in the saturation region, then it acts as a closed switch while in the cut-off region, then it behaves as an open switch. When a zero input signal is applied to the base of the transistor, it acts as an open switch. WebBetween those points you find 24 volts DC, just as it should be. Next you measure voltage between TP2 and ground with the switch pressed and unpressed. With the switch pressed, there is no voltage between TP2 and ground, but there is voltage (about 23.5 volts) when the switch is unpressed. new orleans hotels holiday inn express

"WebJun 11, 2015 · The (small signal) transconductance gm = dIc/dVbe of a BJT is mainly dependent on Ic but since beta = Ic/Ib (assuming we're in the linear region !) you could say that the gm (I would not call that gain as gm has unity [A/V]) is dependent on Ib. But it is more convenient to say the gm is dependant on Ic since gm = Ic/Vt. Share Cite Follow " - Comment on bjt operated as switch
