A parallel plate capacitor with circular plates of radius 
\(R \) is being charged, as illustrated. At the given instant, the displacement current in the region between the plates, enclosed between the radius 
\(\dfrac{R}{2}\) and 
\(R \)  is:
    
	
		
			| 1. | 
			\(\dfrac{3}{4}i\) | 
			2. | 
			\(\dfrac{1}{4}i\) | 
		
		
			| 3. | 
			\({ 3 }i\) | 
			4. | 
			\(\dfrac{4}{3}i\) |
