14. When you added another bulb to the circuit what happened to the brightness of the original load: 13. Light bulbs have filament in them that act as resistors. Resistance in the filament makes the light bulb light up. Notice the reading on the ammeter in series with the 2-load circuit. Did the current increase, decrease, or stay the same? EXPLAIN why. (Think about Ohm's Law and your answers to #3.) 14. Add another battery to your circuit. Use the voltmeter to measure the voltage across each load. a. load 1 b. load 2
