Question

find the total charge through 60uF capacitor

supply 10V​

Answer 1

Answer:

3

Explanation:

the capacitorance before filled with dielectric is C = Aeo/d

the capacitorance after filled with dielectric is C = Akeo/d = kC

initial charge, Q = 60uf and total charge after filled with dielectric Q = 120 + 60 = 180 uC.

here, Q = CV and Q = C¹V = kCV

Q¹/Q = kCV/CV

k = Q¹Q= 180 / 60 = 3

this is ur ans
