Make sure the values button is checked. Calculate the total current of the series circuit with 3 light bulbs. Remember that in a series circuit, the total resistance is the sum of the individual resistances of the light bulbs. Battery voltage: 9 Volts Total resistance of all light Current = 0.3 A bulbs? 10+10+10 = 30 ohms 9/30 = 0.3 I Now, move the voltmeter around to make voltage reading in various places. What do you find? Insert a screenshot of your series circuit in the box below.
