B. Determine the six roots of (717.925 +j126.589). Express in polar form.

In a Ragone plot, which technology has the greatest specific energy   A. Super-Capacitors   B. Ni-Cd batteries   C. lead acid batteries   D. Li-ion batteries

0 Consider the image below. Derive an expression for E as a function of the excitation voltage E¡ and the resistances R₁ and R₂. You may have to use Ohm's law and/or Kirchhoff's laws. Ei allt R1 Eo 0 R2

O d. 16W A Capacitor filter is used at the output across the load in order to minimize the ripple factor of the output voltage. The expressions of the average output voltage VDc and the output AC component VACare given below. If R = 1k2 and the single phase bridge rectifier supplied from a 120V - 50 Hz sinusoidal source, then the capacitor value that will maintain the amount of the output ripples to less than 4% would be equal to: VpC = Vm((4FRC – 1)/4fRC) VAC = Vm/(4/2fRC) Select one: a. 126.2uF O b. 93.39uF Oc. 63.39UF O d. 33.2uF TOSHIBA
