Most Important Selected Qs for JEE AdvancedPhysicsCapacitance
Consider a circuit with a constant current source of I_S=2 ~mA with a capacitor of 2 ~F and resistor of 5 k (as shown in figure). At t=0 the switch is closed. I_C & I_R denotes current in the capacitor & resistor branch respectively and V _ C represents potential difference across the capacitor. Choose the correct graph(s).
Correct answer
3
Step-by-step solution
At t=0 , capacitor act a short circuit & current in resistor branch =0 . At t = , i _ R =2 ~mA ; i _ C =0 .
