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 UsTolerance Calculator (Resistors, Capacitors)
The tolerance percentage is a specification which shows how much an electronic component can deviate, in percentage, from its stated nominal value. For example, if a 1KΩ resistor has a tolerance of 20%, this means it can deviate 20% from its 1KΩ of resistance. 20% of 1KΩ is 200. So the resistance can fall between 800Ω and 1.2KΩ.
