An alternating voltage is connected to a box with some unknown circuital arrangement. The applied voltage and current through the circuit are measured as `(v = 80 sin omega t)` volt and `(i = 1.6sin(omega t + 45^0)` ampere : What is the average power delivered by the box?

An alternating voltage is connected to a box with some unknown circuital arrangement. The applied voltage and current through the circuit are measured as (v = 80 sin omega t) volt and (i = 1.6sin(omega t + 45^0) ampere : Is the circuit in the box at resonance?
