A capacitor of capacitance 5 ~F is connected as shown in the figure. The internal resistance of the cell is 0.5 . The amount of charge on the capacitor plate is

Options

  1. A10 C
  2. B5 C
  3. C6 C
  4. D10.2 C

Correct answer

A. 10 C

Step-by-step solution

We know that capacitor offers infinite resistance for DC source. Current taken from the cell aligned & i= E R+r i & = 2.5 1+1+0.5 =1 ~A aligned Potential drop across capacitor aligned V & =E-i r & =2.5-1 0.5=2 ~V aligned The current in 2 resistor is zero. Charge on capacitor aligned Q & =C V & =5 2=10 C aligned
