To produce an instantaneous displacement current of 2 ~mA in the space between the parallel plates of a capacitor of capacitance 4 F , the rate of change of applied variable potential difference ( d V d t ) must be
Options
- A200 ~V / s
- B400 ~V / s
- C800 ~V / s
- D500 ~V / s
Correct answer
D. 500 ~V / s
Step-by-step solution
aligned & Displacement current i_d=c d V d t & 2 10⁻³=4 10⁻⁶ d V d t & 2 10⁻³ 4 10⁻⁶ = d V d t & d V d t =500 ~V / s aligned
