1. We need to find the unit of 
.
From Maxwell's equations, the displacement current density is given by 
.
The term 
has the same dimensions as displacement current density 
.
Current density 
is defined as current per unit area, 
.
The SI unit of current 
is Ampere and the SI unit of area 
is 
.
Therefore, the unit of current density is 
.
Alternatively, using dimensions:
Dimension of 
.
This corresponds to the unit 
.
