AP 1 Circuits Review 6
A student has four identical light bulbs, sockets and alligator clip wires to assemble the bulbs in a series,
parallel or combination circuit. The student can connect the bulbs to a power source to create a working
circuit.
Draw a circuit showing how the student can assemble a circuit
a.
for the lowest power rating. Explain why this circuit would have the lowest power rating.
b.
where the bulbs are the brightest and each bulb has the same brightness. Would the current in
the battery of this circuit be more than, less than or the same as Circuit a? Explain.
c.
that has a pair of bulbs of equal brightness, and a second pair of bulbs of equal, but less
brightness than the first pair. Identify the brighter pair in your circuit.
d.
that has the lowest voltage drop across each bulb.
e.
that has one bulb brighter than the other three, two bulbs of the same brightness, but less
bright than the fourth. Identify the bulbs as 1 (brightest) 2 (middle brightness) and 3 (least
bright).
