Question

The circuit shown in the figure consists of a battery of emf ε =10V; a capacitor of capacitance C=1.0 µF and three resistor of values R₁ =2 Ω , R₂ =2 Ω and R₃ =1 Ω . Initially the capacitor is completely uncharged and the switch S is open. The switch S is closed at t=0

(A) The current through resistor R₃ at the moment the switch closed is zero. 

(B) The current through resistor R₃ a long time after the switch closed is 5A 

(C) The ratio of current through R₁ and R₂ is always constant. 

(D) The maximum charge on the capacitor during the operation is 5 µC

Answer 1
