In the question number 7, the rate of change of potential difference between the plates is

Answer»

`2.41xx10^(9)VS^(-1)`
`1.87xx10^(9)Vs^(-1)`
`3.2xx10^(-4)Vs^(-1)`
`4.5xx10^(-4)Vs^(-1)`

Solution :Here, C = `80xx10^(-12)F, I=0.15A`
Also q = CV
or `(dq)/(DT)=Cxx(dV)/(dt)"i.eI"=C(dV)/(dt)or(dV)/(dt)=(I)/(C)=(0.15)/(80xx10^(-12))`
or `(dV)/(dt)=(I)/(C)=(0.15)/(80xx10^(-12))=1.87xx10^(9)"V s"^(-1)`
