9:49 I A Current Volta... Saved in Drive Notice three things!! 1: The voltage did NOT divide up evenly. This is because each bulb has different resistance. If they were all the same resistance, the voltage drops would be the same. 2: The total voltage drop (sum for all 3 bulbs) should equal the voltage of the battery. And, with a little error due to rounding it does! 3: For a series circuit or section of circuit, the current is the same through all the devices. Now, let's close the switch and see if we're correct! The first thing you see is that each lightbulb has a different brightness. This should make sense when you consider the voltage at each bulb is different. Then, when we use the Ammeter (measures current), we see the current is: .43 Amps Question: Why does it not matter where we measure the current?
