A larger parallel plate capactior, whose plates have an area of `1m^(2)` are separated each other by `1` mm, is the plates has the dielectric constant `10`, then the displacement current at this instant is:

Options

A. `25 mu` A
B. `11 mu` A
C. `2.2 mu` A
D. `1.1 mu` A

Answer

c

Explanation

`C=(epsilon_(0)KA)/(d)=((8.85xx10^(-12))xx10xx1)/(10^(-3))`
`=8.85xx10^(-8)` F
`i=(d)/(dt)(CV)=C(dV)/(dt)=8.85xx10^(-8)xx25`
`=2.2xx10^(-6)` A
`=2.2mu` A
