Explain the SI Unit of Capacitance. 

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.

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.

The ability to do work on a charge is called the electric potential and the ability to store charge is termed as the capacitance.

After switch ‘S’ is closed

$Q_1+Q_2=C_{1}V$ -    (1)

              Using KVL

              $\frac{Q_1}{C_1}-\frac{Q_2}{C_2}=0$  

              $Q_1=Q_2\frac{C_1}{C_2}$                 &
