At what rate must the potential difference between the plates of a parallel-plate capacitor with a 2.0 μF capacitance be changed to produce a displacement current of 1.4 A?

Respuesta :

Answer:

7 x 10^5 V/s

Explanation:

capacitance, C = 2 micro farad = 2 x 10^-6 F

displacement current, id = 1.4 A

Let dV/dt be the rate of change of potential difference between the plates of the capacitor.

The relation between the displacement current and the rate of change of potential difference is given by

[tex]i_{d}=C\frac{dV}{dt}[/tex]

[tex]1.4=2\times10^{-6}\times\frac{dV}{dt}[/tex]

dV/dt = 7 x 10^5 V/s

Thus, the rate of change of potential difference between the plates is given by 7 x 10^5 V/s.
