Part 2

Draw the standard circuit diagram for the following: (if a bulb does not light, do not draw it) A complete circuit is made of a bulb, battery and some element you can't see because it's in a box. The bulb glows at a certain brightness. Someone changes something in the box, and the bulb glows dimmer than before. No explanations are needed here. What happened to the current through the bulb? What happened to the current through the battery? What happened to the resistance of the circuit? What circuit element could have been in the box initially and what could it have been replaced with? Consider the following circuit: Rank the bulbs by brightness (A-F) with the switch OPEN. Use signs for ranking (>, D>C=E. When the switch is CLOSED in the circuit above....(circle one for each line) State whether the bulbs in the following circuits are arranged in series, parallel, or neither, for the combination of switch positions in the table below. Predict the brightness of the bulbs in each case as well. State whether the bulbs in the following circuits are arranged in series, parallel, or neither, for the combination of switch positions in the table below. Predict the brightness of the bulbs in each case as well.

Explanation / Answer

3.)

1,2,3,4,5 in series

6&7 in parellel

a.) decrease,b.) decrease, c.) increase, d.) resistor----> capacitor

4.) A.) A=B=C=D=E=F

b.) A--no change,B- no change,D- goes off, F-brighter, LESS

5.)

Circuit 1

series, A=B

neither, A>B

neither,A=B

neither, A>B

neither, A>B

neither, A>B

neither, B>A

parellel, A=B

cicuit 2

neither, D>A=B=C

neither, D>A=B=C
