1. A circuit element is shown below, with the voltage v(t) and the current i(t) defined. The voltage and current are given as v (t ) = 5sin (t ) [V] i (t ) = −10cos (t ) [A] . Calculate the power that the element is delivering. b) For the same circuit in the previous problem, calculate the amount of energy that the circuit element absorbs between t = 0 and t = 1 . I don't get the b0 part. The solution for the first part is 50 sin(t) cos(t) [W]. How do I get the amount of energy for that time frame?
