During charging of capacitor, I_C. is the conduction current flowing in the wires connecting capacitor to the battery and I_d is theDisplacement current flowing between the plates of the capacitor.

Answer»

`I_c gt I_d`
`I_c lt I_d `
`I_c= I_d`
No relationexistsbetween`i_c ` and `I_d`

Solution :According to continuity of current conduction current has to be equal to the displacement current hence `i_C =I_D`. We can prove it easily.
Let o be the instantaneous charge ACQUIRED by the PLATES of the capacitor at some instant of time. Electric FIELD between the plates of the capacitor can be written as follows: `E=(q )/(epsi_0 A)`
Electric flux associated with a plane PARALLEL to plates of the capacitor having same area as that of plate of capacitor can be written asfollows:
`phi = EA =(q )/(epsi_0)`
Displacement current can be written as follows:` I_d =epsi_0 ( d phi) /(d t) = ( dq) /( dt)=i_c`
Hence displacement current between the plates of the capacitor is same as conduction current FLOWING in the wires.
