JEE Main2013PhysicsCapacitanceActual
To establish an instantaneous current of 2 ~A through a 1 F capacitor ; the potential difference across the capacitor plates should be changed at the rate of:
Options
- A2 10^4 ~V / s
- B4 10^6 ~V / s
- C2 10^6 ~V / s
- D4 10^4 ~V / s
Correct answer
C. 2 10^6 ~V / s
Step-by-step solution
As, C = Q V = It V aligned & V t = I C = 2 1 10⁻⁶ & =2 10^6 ~V / s aligned
