Note: Use the variable-voltage DC power source as the battery and set it to 9V. a. Determine the resistance of a light bulb using an ohmmeter. Record the value. To do this, the light bulb must NOT be connected to any kind of circuit. b. Construct the following circuits. In each case, draw the circuit diagram and measure the current througth the light bulb(s). Circuit A: Using the battery at the 9V setting, connect a single light bulb across the battery. Circuit B: Add a 100-ohm resistor to circuit A such that the brightness of the light bulb decreases. Circuit C: Add a 100-ohm resistor to circuit A such that the brightness of the light bulb stays the same. Circuit D: Add a second light bulb to circuit A such that it shines visibly, but less brightly than the first light bulb. You can add as many resistors as you want.Alternate light-bulb challenge: c. Create a circuit in which there is simultaneously one light bulb at maximum brightness, and two other ones at roughly half the brightness of the rst one. Your circuit cannot include any resistors ( other than the resistance of the light bulbs themselves ). - On a separate sheet of paper, make a circuit diagram for your setup. Measure the current through each light bulb, and indicate those values on your diagram. Show your working circuit and your diagram to your teacher. d. Create a circuit in which there is simultaneously one light bulb brightly lit, and a second one less brightly lit. ( You can only use two light bulbs, but you can use resistors as well if you want ). - On a separate sheet of paper, make a circuit diagram for your setup. Measure the current through each light bulb, and indicate those values on your diagram. Show your working circuit and your diagram to your teacher. Note: the table has rows for more branches than there are in the circuits. Just ll in as many as there truly are. -__II - list ofelements: total resistance: - -- - - - - 4-Ba 2%, 59 Colo Blac O O ght Bulbs OHN ABBOTT COLLEGE O -LED + O Diode + N O watch polarity!!
