In the case of the mosfet, once you apply a voltage to its gate, it stays that way until you remove it. You could say that the nfet''s base behaves like a resistor, while the mosfet''s gate behaves like a capacitor. In simple words: the mosfet''s gate is like a capacitor that needs to be charged to a certain potential for it to work.

external 10k resistor VS internal pull-up for push buttons

I want to do exactly that, wake up ESP32 from deepsleep using ext1 on one pin, in order to save battery life. The problem I have is about the resistor value: the switch that will pull-down/up the pin state will be closed for 1/3 of the time, so the current passing through the 10k external resistor will render any deepsleep useless.

External resistance coils

Every one that I have looked at (including the GM Delco replacement from the chevy dealer) are stamped "use with external resistor only". The guy at the chevy dealership said "that is the correct replacement according to the book". Are all new coils designed to be used with external resistors or should I keep looking? Dwayne

However, looking at the design recommendations I see that they provide a possible Rext as the external resistor. I read that it can be 0 ohms or 5-6 Rs (series resistance of crystal). Then reading the oscillator design guide provided by ST I see that a series external resistor is needed if the power dissipated through the crystal is higher than what is stated on the crystal datasheet.

6 FAQs about [Capacitor external resistor]

What are resistors & capacitors?

Resistors and capacitors are per-haps the most common elements in all electrical circuits. Even if they are not explicitly shown on circuit schematics, they are present in the physical layout, for example, in the form of the unwanted (parasitic) resistance and capacitance of the wiring.

Does a capacitor have internal resistance?

While an ideal capacitor would have no internal resistance, real-world capacitors do. This internal resistance is known as Equivalent Series Resistance (ESR). ESR represents the combined resistance of various components within the capacitor, including: Electrode Resistance: The resistance of the conductive plates.

Can a resistor be added to a capacitor?

You should realise that the addition of a resistor in the circuit in series with the capacitor ONLY affects the TIME it takes for the capacitor to become fully charge and NOT the EVENTUAL POTENTIAL DIFFERENCE ACROSS IT – this is always the same and equal to the potential difference across the supply. (Figure 1)
