Answer the following points in detail and rigorously. Instead of resorting to formulas, develop from basic principles (laws of voltages and currents, definition of electrical power, properties of phasors, among others). a) Suppose that between the two terminals of an element there is a voltage v (t) and that a current i (t) enters through the terminal marked with a positive sign. Show that if v (t) and i (t) are sinusoidal and are out of phase by an angle ϕ, then the active power P that is consumed by said element is proportional to cos ϕ. b) How much is P for a pure inductor and how much for a pure capacitor?

A voltage is given by v( t )=10 sin(1000πt+30°). First, use a cosine function to express v(t). Then, find the angular frequency, the frequency in hertz, the phase angle, the period, and the rms value. Find the power that this voltage delivers to a 50-Ω resistance. Find the first value of time after t=0 that v(t) reaches its peak value. Sketch v(t) to scale versus time. * Denotes that answers are contained in the Student Solutions files.
