Very good video; i have one question: the circuit will cut the voltage in more or less 50 u seconds (from 12V to 1 V). How we can cut the voltage fasten, ex. in 4 useconds?

Hi...Thanks for your question...you can use comparator based circuit...faster opamp will do the job for you. Incase of short circuit even usually comparator based designed are preferred.

How are the resistor values selected?

Hi. Do you want to to know about any specific resistor. Generally if you know your current flowing through branches and voltage at node ....you can find the resistor.

@ElectronicsCircuitHubECH do the resistor selections impact the current received at the load when in the nominal range? Is there an optimal set of resistors to supply a 5v load at 500mA? Thank you in advance!
