Why doesn't the starting point for summing the voltages around a closed loop make any difference?
Answer:



Kirchhoff's Voltage Law applies to any closed path, even one without current. How did the result of step 11 show that this is true?

Answer:



Based on the result you observed in step 11, what voltage would you expect in a 230 V circuit across an open (blown) fuse?
Answer:
Use Kirchhoff's Voltage Law to find 𝑉𝑥 in Figure 3-6:

Answer:



A 330 Ω resistor is in series with an LED and a +3.3 V source.
a)
If 2.0 V is the voltage across the LED, what voltage is across the resistor?

b)
What is the current in the circuit?
