In step 11, you simulated an open resistor by removing it from the circuit, and you observed that the total current dropped. Explain how the open resistor could be found in this experiment from the observed change in current and the source voltage.
Answer:
If one of the resistors in this experiment were shorted, what would you expect to see happen? (Do not try this!)

Answer:





Three resistors are connected in parallel across a 40 V source. The values of the resistors are 620 Ω, 750 Ω, and 820 Ω.
a)
What is the total source current?
b)
If the measured current was 118 mA, what fault could account for this?
The known currents for a circuit node are shown in Figure 3-18. What is the value and direction of the unknown current, 𝐼4?

Answer:



Could a shorted component in a parallel circuit cause an open to occur elsewhere? Explain.
