10. Under insolation conditions of 500 W/m2 (direct sunlight), and 10% solar cell efficiency (defined as the ratio of electrical output power to incident solar power), calculate the area required for a photovoltaic (solar cell) array capable of running the vehicle in Exec 9 at half power.

24. Two metallic terminals protrude from a device. The terminal on the left is the positive reference for a voltage called ux (the other terminal is the negative reference). The terminal on the right is the positive reference for a voltage called v). (the other tenninal being the negative reference). If it takes I mJ of energy to push a single electron into the left terminal, determine the voltages &kr and vx.

34. Refer to the circuit represented in Fig. 2.33, while noting that the same current flows through each element. The voltage-controlled dependent source provides a current which is 5 times as large as the voltage V. (a) For VR = 100 V and Vx = 92 V, determine the power supplied by each element. (b) Verify that the algebraic sum of the supplied powers is equal to zero.

Chapter 3:

2. Referring to the circuit depicted in fig count the number of (a) nodes; (b) elements; (c) branches.

6. A local restaurant has a neon sign constructed from 12 separate bulbs; when a bulb fails, it appears as an infinite resistance and cannot conduct current. In wiring the sign, the manufacturer offers two options (Fig. 3.48). From what you' vc learned about KCL. which one should the restaurant owner select? Explain.

16. For the circuit of Fig. 3.57:
(a) Determine the voltage u1 if v2 = 0 and v3 = -17 V.
(b) Determine the voltage vl if v2 = -2 V and u3 = +2 V.
(c) Determine the voltage v2 if vi = 7 V and v3 = 9 V.
(d) Determine the voltage v3 if tti = -2.33 V and v2 = -1.70 V.

46. Making appropriate use of resistor combination techniques, calculate i3 in the circuit of Fig. 3.84 and the power provided to the circuit by the single current source.
