26.
If a capacitor C having selectivity factor Q is scaled down in all its dimensions by a factor K without any altering the dielectric material, the new capacitor will have capacitance and selectivity as
C, 
, Q, C, K
Answer: Option
Explanation:
Since the dimension of plates is scaled down by K, the area decreases by a factor of K2, the distance between plates decreases by a factor of K.
Therefore, capacitance changes to 
.
The selectivity will not be affected.
