Electrostatics 7 Question 4

4. In the given circuit diagram, when the current reaches steady state in the circuit, the charge on the capacitor of capacitance C will be

(2017 Main)

(a) CEr1(r2+r)

(b) CEr2(r+r2)

(c) CEr1(r1+r)

(d) CE

Show Answer

Solution:

  1. In steady state no current flows through the capacitor

So, the current in circuit I=Er+r2

Potential drop across capacitor = Potential drop across r2

=Ir2=Er2r+r2

Stored charge of capacitor, Q=CV=CEr2r+r2
