capacitor
The problem is that, if your load have big current requirements, the computed max R value will probably not lead to a realistic C value. So, what people usually do is to use a soft-start circuit using a MOSFET. This way, at steady state, the resistance between the supply and your load becomes negligible (so there is no voltage drop).
Capacitor Motor
The principles of obtaining these features are the same as for the motors previously discussed.

6 FAQs about [Capacitor resistance adjustment principle]
What are the real-world considerations of a capacitor?
Real-World Considerations: Parasitic Resistance: Even in the most ideal circuit, there will always be some resistance, whether it’s from the wires, the internal resistance of the voltage source, or the ESR (Equivalent Series Resistance) of the capacitor itself.
Do capacitors have resistance?
No, capacitors do not have resistance in the same way that resistors do. However, real-world capacitors have an inherent resistance known as Equivalent Series Resistance (ESR). This resistance arises from the materials used in the capacitor’s construction, such as the dielectric and the conductive plates.
What is capacitor reactance?
Capacitive reactance can be thought of as a variable resistance inside a capacitor being controlled by the applied frequency. Unlike resistance which is not dependent on frequency, in an AC circuit reactance is affected by supply frequency and behaves in a similar manner to resistance, both being measured in Ohms.
How do you calculate the resistance of a capacitor?
Capacitors don’t have a fixed resistance. Instead, they have capacitive reactance, which varies with frequency. To calculate it, use Xc = 1/ (2πfC), where Xc is reactance, f is frequency, and C is capacitance. What is ESR and why is it important？
What is the resistance of an ideal capacitor?
The resistance of an ideal capacitor is infinite. The reactance of an ideal capacitor, and therefore its impedance, is negative for all frequency and capacitance values. The effective impedance (absolute value) of a capacitor is dependent on the frequency, and for ideal capacitors always decreases with frequency.
What is capacitor impedance?
It’s a passive electronic component that stores electrical energy in an electric field. However, capacitors exhibit a property called “impedance,” which is a complex number that represents the total opposition to the flow of alternating current (AC) in an electrical circuit. Impedance combines both resistance and reactance.
