In an a.c. circuit, the instantaneous voltage and current are
V = 200 sin 300 t volt and I = 8 cos 300 t ampere respectively. Is the
nature of the circuit capacitive or inductive ? Give reason

It is capacitive circuit because according to the theory, if the phase angle of I lead V by π/2, then its capacitive.
As we know, V implies the function of sine whereas I connects to the function of cosine when there is same angle. Therefore, current leads.
In this circuit, if you calculate power dissipated, it would be 0 W.

Answer:
Capacitive ....
because according to the law, if phase angle of I leads by pie/2 then it is capacitive.
