Stray resistance is an intended resistance in a circuit which is not a design factor, but is present unavoidably.

6 FAQs about [Capacitors reduce resistance in a circuit]
How does resistance affect a capacitor?
The rate at which a capacitor charges or discharges will depend on the resistance of the circuit. Resistance reduces the current which can flow through a circuit so the rate at which the charge flows will be reduced with a higher resistance. This means increasing the resistance will increase the time for the capacitor to charge or discharge.
Can a circuit be reduced to only one resistor and capacitor?
The steps are also iterative. They may need to be repeated multiple times to reduce a circuit to its minimum number of resistors and capacitors. Finally, not all circuits can be reduced to only one resistor and capacitor. The goal is to reduce to the minimum possible number of each. What are Equivalent Resistance and Capacitance?
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.
Are capacitors resistors?
Capacitors are not resistors; they don’t inherently resist the flow of current. So, what’s the deal with “capacitor resistance”? While capacitors don’t exhibit a static resistance like resistors, they do influence the behavior of circuits in ways that can be interpreted as resistance-like behavior. This is particularly evident at high frequencies.
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.
Why does a capacitor charge faster with a small resistance?
As noted before, a small resistance R R allows the capacitor to charge faster. This is reasonable, since a larger current flows through a smaller resistance. It is also reasonable that the smaller the capacitor C C, the less time needed to charge it. Both factors are contained in τ = RC τ = R C.
