What is reflection of light ?

A capacitor is made of two circular plates each of radius 12 cm, and separated by 5.0 cm. The capacitor is being charged by an external source. The charging current is constant and equal to 0.15 A. Is Kirchhoff's first rule (junction rule) valid at each plate of the capacitor? Explain.
