Circle the correct picture of 3 bulbs connected in series to a power source. On the correct circuit, label positive + and negative - on the battery and label the bulbs 1, 2, 3. P2. On the correct circuit (the far right one), draw ammeters to measure the conventional positive (+) current into the other bulbs and into the power source for a total of 4 ammeters. Label the end of the ammeter connected toward the positive (+) terminal of the power source with a positive (+) indicating how you will connect the ammeter. Part II. MEASURING VOLTAGE in Series Circuits P4. On the correct circuit, now add voltmeters to measure the voltage across each bulb and the power source for a total of 4 voltmeters. On the correct circuit, label positive + and negative - on the battery and label the bulbs 1, 2, 3. P5. You will now measure the voltages in the circuit using only 1 voltmeter by measuring the voltage of each part separately. Connect your correct circuit as in P4 without the voltmeters. Now with your probes and without disconnecting any bulbs, touch the wires on either side of bulb 1. A positive reading means the red probe is at a higher voltage than the black probe. Now measure the voltage across the battery. Probes should be placed in the circuit so the current direction is from red probe to black probe Repeat the measurements across all resistors and across the power supply.
