JEE Main & Advanced Physics Electrostatics & Capacitance Question Bank Self Evaluation Test - Electrostatic Potential and Capacitance

  • question_answer
    Three condenser each of capacitance 2F are put in series. The resultant capacitance is 

    A) 6 F       

    B) 3/2 F

    C) 2/3 F    

    D) 5 F

    Correct Answer: C

    Solution :

    [c] Capacitance are in series \[\frac{1}{c}=\frac{1}{2}+\frac{1}{2}+\frac{1}{2}\Rightarrow c=\frac{2}{3}F\]
