The clear sky appears blue because:
A capacitor is charged by using a battery which is then disconnected. A dielectric slab is then slipped between the plates, which results in
|
(a) Reduction of charge on the plates and increase of potential difference across the plates |
|
(b) Increase in the potential difference across the plate, reduction in stored energy, but no change in the charge on the plates |
|
(c) Decrease in the potential difference across the plates, reduction in the stored energy, but no change in the charge on the plates |
|
(d) None of the above |
Assertion : A transistor amplifier in common emitter configuration has a low input impedence.
Reason : The base to emitter region is forward biased.
|
(a) If both assertion and reason are true and the reason is the correct explanation of the assertion. |
|
(b) If both assertion and reason are true but reason is not the correct explanation of the assertion. |
|
(c) If assertion is true but reason is false. |
|
(d) If the assertion and reason both are false. |

While a capacitor remains connected to a battery and dielectric slab is applied between the plates, then
|
(a) Potential difference between the plates is changed |
(b) Charge flows from the battery to the capacitor |
|
(c) Electric field between the plates increases |
(d) Energy store in the capacitor decreases |
