L8Q1 L8Q2 What is the voltage drop across an ideal ammeter What is the current through an ideal voltage source? L8Q3 Which set of graphs corresponds to pure resistances? 0 V 0 A B. Even negative slope are possible if the current polarity is "uphill" to the defined voltage polarity. L8Q4 What are the IV characteristics of the circuit above? Include the graph. L8Q5 L8Q6 What are the IV characteristics of the circuit above? Include the graph. What are the current values I when V equals 0, 2V, 4V? Your instructor most likely defined voltage polarity with the + on top, but might have defined current polarity either direction. Both of these solutions are provided below. We will assume the first solution in the rest of the answers below. same as circuit in Q4 3/2, 4, 13/2 A L8Q7 L8Q8 L8Q9 L8Q10 What are the current values I1 when V1 equals 0, 2V, 4V? What are the IV characteristics of a 3 mA current source? Use polarities defined in sub-circuit 2. What are the IV characteristics of a 3kΩ resistor? Use polarities defined in subcircuit 2. Considering the three choices for circuit #2 - a 3mA current source, a 3kΩ resistor, or a combination with IV characteristics I(mA)=(1/3)*V - 3, what is the operating point when the 2 su-circuits are connected? Which sub-circuit supplies the power? -11, -8.5, -6 I=-3mA I=(1/3000)*V With the polarity of the voltage relative to the current direction of subcircuit 2 the current must be negative when the voltage is positive (or vice versa but this is never the case) A
