While an ideal capacitor in theory does not have any resistance, practical capacitors do exhibit resistance in the forms of ESR and leakage resistance. A capacitor does have some resistance in practical sense. Whenever a capacitor gets charged, current flows into one of the plates and current flows out of the other plate and vice versa.
A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
Both capacitors and resistors are important components in circuits, especially delay or timer circuits. Combining resistors and capacitors in a circuit will increase / decrease a timing sequence. A simple circuit is shown shows four capacitors and resistors in parallel.
There are several other factors that go into this decision including temperature stability, leakage resistance (effective parallel resistance), ESR (equivalent series resistance) and breakdown strength. For an ideal capacitor, leakage resistance would be infinite and ESR would be zero.
This is the resistance due to the leakage current that flows through the dielectric material of the capacitor when a voltage is applied across it. Ideally, this should be very high, indicating very low leakage current, but in real capacitors, it is finite.
Combining resistors and capacitors in a circuit will increase / decrease a timing sequence. A simple circuit is shown shows four capacitors and resistors in parallel. On the left hand side of the circuit an LED is seen, this is protected by a 300 ohm resistor.
