A parallel plate capacitor is made of two dielectric blocks in series. One of the blocks has thickness d1and dielectric constant K1 and the other has thickness d2 and dielectric constant K2 as shown in figure. This arrangement can be thought as a dielectric slab of thickness d (= d1 + d2) and effective dielectric constant K. Then K is
It is the farad (F). The name came from Michael Faraday. SI Unit of Capacitance means the ability of a system to store an electric charge. One farad is the capacitance of a device that needs one coulomb of charge to provide one volt potential difference across it. Mathematically, it is represented by - 1 Farad = 1 Coulomb/Volt.
In JEE Main Physics, electric potential and capacitance chapter has a weightage of 3% to 6%. You can expect around 1 or 2 questions from this chapter which carries 4 to 8 marks.
In NEET Physics exam, the chapter electric potential and capacitance carries a weightage of 2% to 5%, which means you can expect one question out of 45 questions.
