Question

a. Rank bulbs A-F in the diagram above from brightest to dimmest.

b.

Consider again the circuit above. (The circuit is identical to that in problem CK5_part 1.)

Suppose that bulb E in the circuit is unscrewed and taken out of the socket. The socket is left in the circuit. (Note that even though the socket is left in the circuit, there is no conducting path through the socket anymore.)

Will the brightness of bulb A increase, decrease, or stay the same?

Will the brightness of bulb F increase, decrease, or stay the same?

Will the brightness of bulb B increase, decrease, or stay the same?

Explanation / Answer

bulb a is in series with the others so brightness gets decreased

bulb f is in parallel so it gets increases its brightness

bulb also decreases its brightness
