Assertion : The displacement current is always equal to the conduction current.
Reason : The displacement current is given by,
Id = \(\varepsilon_{0} \frac{d \phi_{\mathrm{E}}}{d t}\)
It leads to,
Id = \(\frac{d q}{d t} \ldots\) \(\left(\because \phi_{E}=E \times A=\frac{q}{\varepsilon_{0} A} \times A=\frac{q}{\varepsilon_{0}}\right)\)
Id = Ic
