  • Question 1/10
    4 / -1
    A parallel plate consider with oil between the plates (dielectric constant of oil K = 2) has a capacitance C. If the oil is removed, then capacitance of the capacitor becomes
    Solutions

  • Question 2/10
    4 / -1
    A parallel plate capacitor has circular plates of 0.08 m radius and 1.0 × 10–3 m separation. If a P.D. of 100 volt is applied, the charge will be
    Solutions

  • Question 3/10
    4 / -1
