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

JEE Main 2017 (Offline) Physics - Capacitor Question 134 English

Multiple Choice Options

  • A CEr1(r1+r)
  • B CE
  • C CEr1(r2+r)
  • D CEr2(r+r2)

Step-by-Step Verified Solution

In steady state, flow of current through capacitor will be zero.

Current through the circuit,

i = Er+r2

Potential difference through capacitor

Vc = QC = E - ir = E - (Er+r2)r

∴ Q = CEr2(r+r2)
