SERIES CIRCUITS LAB - Weebly



Name: ___________________________________SERIES CIRCUITS LAB – Using GizmosPurpose: Why was this investigation done?____________________________________________________________________________________________________________________________________________________________________Hypothesis: What do you think will happen to the brightness of the lamps when 1, 2, and 3 are connected in series?__________________________________________________________________________________________________________________________________________________What do you think will happen to the voltage?__________________________________________________________________________________________________________________________________________________What do you think will happen to the current?__________________________________________________________________________________________________________________________________________________Procedure:1. Connect the circuit as shown in figure 1. Observe and record in your observation table.2. Connect two lamps in series as in figure 2. Observe and record in your observation table. Disconnect any lamp and observe what happens.3. Connect three lamps in series as in figure 3. Observe and record in your observation table. Disconnect any lamp and observe what happens.Figure 3Observations: Complete the table of observations of what happens as more lamps are connected in series.Table SEQ Table \* ARABIC 1: Series CircuitNumber of LightsBrightnessVoltageCurrent123Analysis:1. Describe the brightness of one lamp connected in the circuit compared to when two lamps were connected in series?__________________________________________________________________________________________________________________________________________________________________________2. What happened to the other lamp when one lamp was disconnected? Explain why. __________________________________________________________________________________________________________________________________________________________________________3. How was the brightness affected when three lamps were connected in series? __________________________________________________________________________________________________________________________________________________________________________4. Why is it impractical to connect the lights in a house in series?__________________________________________________________________________________________________________________________________________________________________________5. What would happen if more lamps were added in a series circuit?__________________________________________________________________________________________________________________________________________________________________________Discussion: On a separate piece of paper answer questions 1-5 on page 141 in your textbook. ................
