Question

In the circuit shown above, the battery supplies a constant voltage V when the switch S is closed. The value of the capacitance is C, and the value of the resistances are R₁ and R₂.

A long time after the switch has been closed, the current supplied by the battery is

(A) V/(R₁ + R₂) 

(B) V/R₁ 

(C) V/R₂ 

(D) V(R₁ + R₂)/R₁R₂ 

(E) zero

Answer 1

The correct option is: (A) V/(R₁ + R₂) 

Explanation:

When the capacitor is fully charged, the branch with the capacitor is “closed” to current, effectively removing it from the circuit for current analysis.
