- Please answer the following points in detail and rigorously. Instead ofresort to formulas, develop from basic principles (laws ofvoltages and currents, definition of electrical power, properties ofphasors, among others) a) Suppose that between the two terminals of an element there is a voltage v (t) and that through the terminal marked with a positive sign a current i (t). Show that if v (t) and i (t) are sinusoidal and are out of phase an angle θ, then the active power P which is consumed by this element is proportional to cosθ. b) How much is P for a pure inductor and how much for a capacitor pure? Does this make physical sense? c) When the power factor seen between two terminals is specified, Why is it necessary to indicate whether it is late or early? d) Show that the complex power consumed by two elements in parallel is the sum of the individual complex powers. After, repeat the procedure but for two elements in series. e) What meaning would you give to the P consumed by an…The electrical model of a biopotential electrode is given belowwith the given values.

The generator’s Thevenin equivalent circuit has V T of 120 V DC and the equivalent resistance, R T , of 10 Ω. There are two resistive heaters inside the tent: R 1 = 10 Ω and R 2 = 120 Ω , that can be connected to the generator separately, in series, or in parallel. For the highest heater power output, how should the heaters be connected to the generator?Explain the principles of microgrids and their potential benefits in providing localized power solutions.
