A parallel plate capacitor with air as dielectric has a capacitance C. If the dielectric has a dielectric constant ∈r and the remaining dimensions are the same, the capacitance will be
Answer: Option
Explanation:
Capacitance ∝ ∈r.
47.
Assertion (A): When excited by a unit step voltage, an inductor behaves as open circuit at t = 0.
Reason (R): Inductance has the property of inertia.
Answer: Option
Explanation:
Because of inertia the current cannot change instantaneously. Therefore it behaves as O.C. at t = 0.

A bulb rated at 60 W, 120 V is used for 30 minutes. The charge associated with this operation is
Answer: Option
Explanation:
49.
Two coil have their axis perpendicular to each other. The coefficient of coupling k is
Answer: Option
Explanation:
When axis are perpendicular then there is no mutual coupling.
50.
