  • Question 1
    4 / -1

    In a parallel plate capacitor, the capacity increases if

  • Question 2
    4 / -1

    A parallel plate capacitor has two square plates with equal and opposite charges. The surface charge densities on the plate are +σ and −σ respectively. In the region between the plates the magnitude of electric field is:

  • Question 3
    4 / -1

    A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates

  • Question 4
    4 / -1

    A parallel plate capacitor is charged and then isolated. What is the effect of increasing the plate separation on charge, potential, capacitance, respectively?

  • Question 5
    4 / -1

    A parallel plate capacitor is connected to a battery as shown in figure. Consider two situations
