Ask a Question
(a) Dielectric constant of the mica sheet, k = 6
Initial capacitance, C = 1.771 × 10 -11 F
New Capacitance, C'= kC= 6x1.771x10-11 =106 pF
Supply voltage, V = 100 V
New Charge, q'=C'V=6x1.771x10-9 =1.06x 10-8 C
Potential across the plates remains 100 V
(b) Dielectric constant, k = 6
Initial capacitance, C = 1.771 × 10-11 F
New Capacitance, C'= kC= 6x1.771x10-11 =106 pF
If supply voltage is removed, then there will be no effect on the amount of charge in the plates.
Charge = 1.771 × 10- 9 C
Potential across the plates is given by,
