It is possible that OP question has another meaning, namely, "After turning on the power, in what state are the outputs of the circuit? Which is HIGH and which is LOW?" (more) |

@Elliot Alderson, Are you happy with my answer? If this circuit solution seems too complicated to you, I will offer you an even simpler recipe for "converting" SPST into SPDT switch - only through a "pulling" resistor. It was dominant before the complementary stage was invented... (more) |

A: Is it possible for one transistor to switch between two loads? When, two months ago, I accidentally found out about the new Codidact platform, I was happy and decided to take part in it. I wanted to mark this event with an interesting question that would arouse the interest of visitors to the new platform. Thus I remembered an interesting inventive idea from the... (more) |

... So far, the transistor is able to resist the input voltage through its emitter voltage. Now the latter disappears and the input voltage is applied directly through the base-emitter junction to the emitter (load). In some cases, this is undesirable... and in others it can be useful. BTW we can obs... (more) |

@coquelicot, Thanks for the comprehensive explanation. I imagined something similar but now it is quite clear to me. As you probably noticed, in my circuit stories I try to show non-standard circuit ideas. My goal is to arouse interest in creative thinking leading to invention of circuits. In this st... (more) |

A: How to plot the I-V curve of a tunnel diode? Setup We can best understand the behavior of the tunnel diode in the region with negative resistance if we imagine it as a self-variable (dynamic) resistor R driven by a variable voltage source V - Fig. 1. If OP has a subtle sense of humor, I suggest we conduct this experiment in the form of a f... (more) |
