Jun 20, 2023 · The discharge input, which is Vcc to the transistor, takes the voltage over Rb. The capacitor will discharge when the transistor is closed, meaning Vcc > base voltage on the …

Apr 9, 2021 · 6 What does a FET actually do? A FET is a transistor which uses the field effect to control current flow. The trick is that applying a (constant) electric field does not need any …

Jun 14, 2016 · A transistor is a crucial component in modern electronics, functioning as both an amplifier and a switch. It is made of semiconductor materials, typically silicon, and has three …

Oct 3, 2020 · This explanation contains some simplifications: I do not talk about base-emitter voltage drop for transistors and the like, but for this particular circuit they should not have …

Mar 25, 2025 · A transistor in an LDR circuit acts as a switch that turns on or off based on light levels detected by the LDR. In bright conditions, the LDR's low resistance prevents the …

May 6, 2019 · The transistor Iout versus Vout characteristic does have a slope, which we label the Early Voltage and model as a straight line; that line does not pass thru (0,0), but you can …

Mar 1, 2021 · I just can not understand why it is that variations in the base current should amplify the current through the transistor. If I am understanding correctly, if we apply a current on a …

Jan 22, 2020 · I am having a very hard time understanding when exactly a transistor turns on. For example in the following circuit from Everycircuit: Why does the transistor turn on when the …

Jan 25, 2023 · When the transistor is on, the current still passes through the collector resistor, but the equivalent resistance of the transistor between emitter and collector is much lower than the …

Apr 3, 2011 · How the transistor works when it is saturated? Is it possible to have the transistor in open state, under some condition other than having Vbe lower than the threshold? In addition, …
