Can you describe your algorithm in words or pseudocode? It's not clear what you are trying to accomplish and where you are stuck. (more) |

You begin with a false premise. Many, many semiconductor devices are not named as you describe. (more) |

Is this homework? Can you provide a link to the datasheet for the MOSFET? (more) |

Of course you can. The siunitx package is ideally suited for this. (more) |

I also think this is a bad answer. There are several statements made that are incorrect or misleading, and I don't care that an experienced engineer will know what Kranulis means...I care that an unexperienced reader will be seriously confused. "can switch loads that are in Drain"...PMOS also switch ... (more) |

The question in the video is incredibly ambiguous. One can talk about the speed of transmission of an electromagnetic field but turning on a light bulb is another matter altogether. While some tiny amount of energy may be transmitted through free space over a distance of 1 m, to say that the light wi... (more) |

It sounds like you are saying that you didn't finish an assigned laboratory exercise, so you are looking for the appropriate values you can use to "fake it". If that's not the case and you really want to know then you need to find a proper datasheet for the meter. (more) |

Can you tell us where you are getting the images you copied into this answer? It looks like you are just taking homework questions and turning them into questions and answers. (more) |

The essence of the ideal current source is quite simple, and trying to convert it to a voltage source and some kind of magic dynamic resistor only makes it harder to understand. The ideal current source is a primitive element; it is not composed of other elements. I think your "intuitive" explanation... (more) |

A passive current source can indeed be a "source"; it can be an ideal current source. Do not assume that an ideal voltage source or ideal current source provides power to the circuit, or that they actually create their voltage or current. The role of an ideal source is simply to constrain the voltage... (more) |

A "voltage source and an infinitely high resistance in series" is only a current source if you want zero current. An ideal current source does not need to "consist" of anything, it is an elemental unit in itself. Its function is to constrain the current flowing through it. (more) |

When you formally write equations, please remember that the symbols used for SI units, such as A for amperes and V for volts, are **not** italicized. An italic *V* is a variable, and upright V is the symbol for volts. (more) |

@JohnDoea You missed the possibility that nothing is coming out of your machine. Your two states are providing water or not providing water. Don't confuse an *output* with a *state*. (more) |

I don't see anything in the Wikipedia article you linked that talks about there being 3 states for spintronics. Can you clarify, or provide another reference? When you talk about charge or no charge, what is the physical thing that either has charge or does not have charge? Just as we know that it is... (more) |

A: A signal with one mode or with three or more modes A "discrete" signal can only have a one of a fixed number of values, rather than a continuous value like real numbers. If that fixed number is two then we say that we have a binary system, or a binary signal. It is convenient to describe these states as 0 and 1, but we could also call them "on" and "... (more) |

I just wanted to clarify that "spin" only has two states, commonly known as up or down. There is no condition or mode where the there is "no spin", which is what you imply in your list of states for spintronics. (more) |

A: 3+3 doesn’t show 6 For the benefit of later readers, I thought I would explain why the original circuit "didn't work" and how exactly the "correct" circuit differs from the original circuit. The issue is the 3-input XOR gate in the original circuit. The behavior of an XOR gate with more than 2 inputs is not precisel... (more) |

If you know how to perform a desired operation with a loop and storage, you just need to unroll the loop. Instead of having multiple iterations of the loop you will have multiple instantiations of the hardware. You can also eliminate the registers for intermediate values if you can guarantee that the...

My problem with your writing is that you misuse language to the extent that it confuses inexperienced readers. The fact that you feel the need to "surround" misused "words" with quotes is "revealing". (more) |

A: Why isn't voltage of electric chair higher? I think your grandfathers story is, shall we say, apocryphal. You should know that electrocution kills by stopping the heart (or causing fibrillation), and the heart must be kept from beating long enough for the person to die. It only takes a few mA to accomplish this and there is no benefit...no ... (more) |

In the olden days I liked to use the example of a touch-tone telephone. Each tone was a baud, and each tone transmitted 4 bits. Conversely, plain old UARTs have a bit rate that is lower than the baud rate. (more) |

A: Is it possible for one transistor to switch between two loads? I suspect this is another of your trick questions and you are waiting for the chance to show us your unrivaled knowledge, but I will play the straight man for you. No. By definition, an SPST switch can not act as an SPDT switch in general. If that were possible then there would be no need to manuf... (more) |

A: Why there is a body diode in mosfets? If your studies lean toward VLSI design rather than discrete circuit design then you may have also learned that a MOSFET is really a 4-terminal device: gate, source, drain, and body. In VLSI design it is common to connect the bodies of all NMOS transistors to the lowest voltage in the circuit (ground... (more) |
