Contact UsResistance of capacitors
A capacitor has an infinite resistance (well, unless the voltage gets so high it breaks down). The simplest capacitor is made from two parallel plates with nothing but space in between - as you can guess from its electronic symbol. In a DC circuit, a capacitor acts as an open circuit and does not permit current to pass.

Contact UsResistance of capacitor
When capacitor voltage reaches source voltage, current flow is nearly zero, dependent on dielectric resistance (leakage current). Apparent capacitor resistance is then very high. So, the apparent "resistance" of a capacitor is not fixed, but varies between nearly zero and nearly infinity. The capacitor therefore "resists" a change in voltage.
Contact UsCurrent when capacitor and resistor placed in parallel?
