A network of resistance cell and capacitor `C(=2 mu F)` is In steady state condition the change on `2 mu F` capacity is `Q` while `R` is unknown resistance value of `Q` and `R` are resistance

Options

A. `2mu C and 2 Omega`
B. `4mu C and 4 Omega`
C. `4mu C and 10 Omega`
D. `8mu C and 4 Omega`

Answer

c

Explanation

In steady state no currect will flow through capacitor using kirchhoff's voltage law to the circuit `ACD` we have

`+10+2= 1xxR+1xx2 or R = 10 Omega`
pot diff across `C` and `D,V_(C)- V_(D)= 2xx1=2V`
As `V_(D) = 0V or V_(C) = 2V`
pot on capacitor `= 4- 2= 2V`
Charge on capicator `Q= 2Vxx 2 mu F = 4 mu C`
