Given in the figure, calculate the resistance of each resistor represented by the two lines.

Using Table 2 of your data, how does the resistance of the individual light bulbs compare to the total resistance of the series circuit?

In the activity for complex circuits, bulbs of the same wattage are used. Would the results you observed be the same or different if each bulb was a different wattage? Assume bulb one is the lowest wattage and bulb three is the highest.

Using Table 4, how does resistance in a parallel circuit affect bulb brightness? Is there any difference in the brightness of bulb one versus bulb three when all bulbs are in the sockets? Why or why not?

When one bulb was removed from your series circuit, what happened to the other two bulbs? Why?

When one bulb was removed from your parallel circuit, what happened to the other two bulbs? Why?

Explain what happens to the current traveling through a light bulb in a parallel circuit when an additional light bulb of equal resistance is added in parallel.

A series circuit has three light bulbs of equal resistance. What happens to the total resistance of the circuit if a light bulb is removed from the circuit?

A parallel circuit has four light bulbs of equal resistances. What happens to the total resistance of the circuit if an additional light bulb is added in parallel to the others?

A parallel circuit with light bulbs has a total current of 5 amps. Two of the light bulbs measured at 2 amps each. What is the current flowing through the third light bulb? Explain how you know.
