A p-n junction solar cell has Voc = 0:5 V and Jsc = 20 mA/cm2. A second cell, of the same area, has Voc = 0:7 V and a short circuit current density of Jsc = 12 mA/cm2. You should have no trouble with writing the equation in terms of current or current density as the situation merits. Assuming that both cells obey the ideal diode equation, Eq. 1, find the values of Voc and Jsc when the two are connected in parallel?

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
