The plastic insulation needs to be stripped back on the end of each wire. same voltage (5S, andn in figures 1-11, follow the instructions below. All batteries have the a) If a circuit diagram is presented ir 1) For each of the situati all bulbs have the same resistance (R). the figure, make a simple physical battery Energy picture of the batteries, bulbs and wires showing how they are arranged. If the figure depicts a physical picture, draw a circuit diagram that corresponds to it Connect the actual batteries and bulbs with wires in ways that match how you have drawn them. Observed the brightness of each bulb, and indicate this brightness on your diagram. Decide if each bulb is b) c) 4: Very Bright, 3: Bright, 2: Standard, 1: Dim, 0: Not Lit Let us define standard brightness (2) as the brightness of the bulb in figure #2. Double check that any bulb you label as 0 is truly not lit, 10. rather than being extremely dim. You may need to go to a dark place to do this. d) Make sense of the relative brightness of the bulb(s) in terms of current(s) through each lightbulb. Write down the current for each lightbulb in terms of ε and R. Use the basic concepts of charge conservation and energy conservation as expressed in the complete energy-density equation for electric circuits in your 6. explanation. Refer to Activity 5.9 A) 1) and 2) л)

Explanation of observed brightness of bulbs connected to battery/batteries

Explanation of observed brightness of bulbs connected to battery/batteries a) an current O (circuit incomplete) current I = epsilon/R current, I = 2 epsilon/R Current, I = 2 epsilon/R current, I = 2 epsilon/2 R = epsilon/R current, I = epsilon - epsilon/2R = 0 I_2 = 2 - epsilon/2 R = epsilon/R I_1 = 0 \r\n T_1 = epsilon/R T_2 = 0 I = 2 epsilon/3 R = 2 /3 epsilon/R Req = R times 2 R/ R + 2 R = 2 R^2 /3R = 2/e R I = 2 sigma/R_eq = 3 sigma/R T_1 = T times R/2 R I = 2 epsilon /R We found the brightness's alpha I^2 (as R is same for all bulbs)
