2.14 Tho voltage atrd cunent werc measured at the ter- minals of ttre device shown in Fig. P2.14(a). The results are tabulated in Fig. P2.14(b). a) Construct a circuit model for this device using an ideal current source and a resistor, b) Use ttre model to predict the amount of power the device will deliver to a 5 O resistor. 51 Use your circuit model to predict the open-circuit voltagg of the current souice. Wlat is the actual open-circuit voltage?
