JEE Main & Advanced Physics Current Electricity, Charging & Discharging Of Capacitors / वर्तमान बिजली, चार्ज और कैपेसिटर का निर Question Bank Grouping of Resistances

  • question_answer
    There are 8 equal resistances R. Two are connected in parallel, such four groups are connected in series, the total resistance of the system will be                                                                                                                                [MP PMT 1987]

    A)            R / 2

    B)                                      2 R

    C)                    4 R                                    

    D)            8 R

    Correct Answer: B

    Solution :

                 Resistance of parallel group \[=\frac{R}{2}\]                    \[\therefore \]Total equivalent resistance = \[4\times \frac{R}{2}=2R\]
