NEET Physics Current Electricity, Charging & Discharging Of Capacitors / वर्तमान बिजली, चार्ज और कैपेसिटर का निर NEET PYQ-Current Electricity Charging Capacitors

  • question_answer
    A parallel plate capacitor of capacitance 20 \[\mu F\]is being charged by a voltage source whose potential is charging at the rate of 3 V/s. The conduction current through the connecting wires, and the displacement current through the plates of the capacitor, would be, respectively:                                                                                         [NEET 2019]

    A)  60 \[\mu A\], zero

    B)       zero, zero

    C)  zero, 60 \[\mu A\]

    D)       60 \[\mu A\], 60 \[\mu A\]

    Correct Answer: D

    Solution :

    [d] Displacement current
    \[i=C\frac{dV}{dt}\]
    \[=20\times {{10}^{6}}\times 3\]
    \[=60\mu A\]
    in circuit displacement current = conductor current.
