1/C = 5/ (ε? × 100) + 5/ (10ε? × 100)
⇒ C = (ε? × 1000) / 55 = (8.85 × 10? ¹² × 1000) / 55 = 1.61 × 10? ¹? F = 161 pF

This chapter covers the concepts of potential, capacitors, and potential energy. It is considered as one of the easy chapter of the class 12 Physics.
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.
