Unformatted text preview: voltage stays the same? How much power will the circuit now consume? R L-V OUT + R I OUT V CC Figure 3: Resistor “current source” 5. Consider the circuit shown in ±igure 3. Let V CC = 10 V and R = 10 kΩ. Roughly sketch I OUT vs. V OUT (space is provided on next page). Note: The specifc value For R L is not required For this analysis. 6. ±ind the short-circuit output current and the output impedance oF the current source. Note: R L represents a hypothetical load to the circuit; it can be replaced with an open-circuit For this analysis. 3-1-. 8-. 6-. 4-. 2 . 2 . 4 . 6 . 8 1 I OUT (mA) 10 20 V OUT (V) 7. For the current source, is it possible to increase the output impedance without decreasing the output current and without changing V CC ? Explain....
