I_ d = \varepsilon _0 \frac{d \theta _\varepsilon }{dt} = \frac{\varepsilon _ 0 d ( E \cdot A )}{dt } \: \: \:......( \because E\cdot d = V \\\\ C = \frac{\varepsilon _0 A }{d }) \\\\ = \frac{\varepsilon _ 0 d ( VA )}{ddt } \\\\ I_D = C \frac{dv }{dt} = 20 \times 20 \times 10 ^ {-6 } \times 3 \\\\ I_D = 60 \mu A \\\\

For \: \: charged \: \: capacitor \: \: I_D = I_C \\\\ I_C = 60 \mu A


Option 1)

zero, 60 \mu A

Option 2)

60 \mu A , 60 \mu A

Option 3)

60 \mu A , zero

Option 4)

zero , zero
