Example 4.7 Find v, in Fig. 4.20 using source transformation. Solution: The circuit in Fig. 4.20 involves a voltage-controlled dependent current source. We transform this dependent current source as well as the 6-V 0.25v independent voltage source as shown in Fig. 4.21(a). The 18-V voltage source is not transformed because it is not connected in series with any resistor. The two 2-N resistors in parallel combine to give a 1-N resistor, which is in parallel with the 3-A current source. The current source is transformed to a voltage source as shown in Fig. 4.21(b). Notice that the terminals for Uy are intact. Applying KVL around the loop in Fig. 4.21(b) gives 6 V 18 V Figure 4.20 For Example 4.7. -3 + 5i + vx + 18 = 0 (4.7.1)

4.68 Using the exponential diode characteristic, show thatfor vS and vO both greater than zero, the circuit of Fig. 4.23(a)has the transfer characteristicvO= vS−vDat iD=1 mA−VT lnvO/Rwhere vS and vO are in volts and R is in kilohms. Note thatthis relationship can be used to obtain the voltage transfercharacteristic vO vs. vS by finding vS corresponding to variousvalues of vO.

One can assemble a “virtual” solar cell array by using playing cards, or business or index cards, to represent a solar cell. Combinations of these cards in series and/or parallel can model the required array output. a) Assume each card has an output of 0.5 V and a current (under bright light) of 2 A. Using your cards, how would you arrange them to produce an output of 6 A at 3 V (i.e. - 18 W)? b) Suppose you were told that you needed only 18 W (but no required voltage). Would you need more cards to make this arrangement?
It is desired to obtain the Thevenin equivalent of a non-ideal battery.
