DC Simulation Basics - Series And Parallel Resistors
In this video we are experimenting with basic series and parallel resistors and their behavior at DC. This is a great first video to watch if you're just getting started with CircuitLab, as it covers some of the basics of simulating and exploring circuits in CircuitLab.
We cover how CircuitLab's Live DC feature continuously simulates your circuit in the background. This feature allows you to see voltages, currents, and other useful information DC about your circuit in real time.

Surprising COVID-19 Strategy: Reduce Economic Damage and Deaths Simultaneously
Просмотров 1,2 тыс.4 года назад
There is no tradeoff between saving lives and saving the economy. I analyze the COVID-19 pandemic as a feedback control system from an engineering perspective, and show something surprising: the shape of the policy frontier is concave down, like an inverted parabola, so that in one region of the curve, it’s not a zero-sum game. It’s optimal to both save lives and save the economy at the same ti...

    Why do you have to input the "behaviour" manually?! Should it not be included in the logic itself? It's quite tiring to input all rules by hand?

    This tool is awesome. Having no formal electronic education, I've always been intimidated by simulators. I just completed this lesson along with the video, simple, no complex formulas and direct. There's a LOT of devices listed on the BUILD panel, so I can only assume this can help me develop circuits for a long time. Congrats CircuitLab! You've made another fan.

  • @cyrilmechkov3119
    @cyrilmechkov3119 Год назад

    An impressive movie... I have only one remark: The voltage across Re does not follow the input voltage simply because the base-emitter voltage is nearly constant and transfers the input voltage to the emitter. This would be the case if the collector of the transistor was left unconnected. The voltage across Re is not created by the input voltage by passing the input current through Re but by the transistor that changes its collector current through Re to set the voltage across it (almost) equal to the input voltage. This is actually the principle of negative feedback.

    Why is ground required? If this was an actual circuit with a real battery, resistor and LED there wouldn't be a ground. Thanks. :-)

      it makes probing easier. without ground, all of your voltage levels are floating.

    Would this circut limit any load bearing circuit, rather than a LED, regardless of what total resistance the load circuit has? Meaning, i have a small circuit of chips, and I want to limit total current to 18ma, can I just take the LED out and replace with my small circuit?
