Question

A capacitor of capacitance ‘C’, is connected across an ac source of voltage V, given by V=V0sinωt The displacement current between the plates of the capacitor, would then be given by

• A. $I_d=V_0\,\omega Csin\omega t$
• B. $I_d=V_0\,\omega Ccos\omega t$
• C. $I_d=\frac{V_0}{\omega C}cos\omega t$
• D. $I_d=\frac{V_0}{\omega C}sin\omega t$

Answer 1

Answer: (B)

$I_d=V_0\,\omega Ccos\omega t$

Answer 2

The correct answer is option (B): $I_d=V_0\,\omega Ccos\omega t$
