1.

1.                 Create a circuit with one bulb.

a.                 Draw a circuit diagram. Be sure to label voltages and resistances.

b.                 Calculate the current through this circuit using Ohm’s Law.

 

2.                 Create a series circuit with two bulbs then three bulbs.

a.                 Draw a circuit diagram for the three bulb circuit. Be sure to label voltages and resistances.

b.                 Calculate the current through this circuit using Ohm’s Law. (Hint req=r1+r2+r3) Measure and record/label the potential difference across each bulb.

c.                  Unscrew the middle bulb. What happens? Why?

 

3.                 Create a parallel circuit (by piggybacking bulbs to each other) with two then three bulbs.

a.                 Draw a circuit diagram. Be sure to label voltages and resistances.

b.                 Calculate the current through each bulb using Ohm’s Law. Measure and record/label the potential difference across each bulb.

c.                  Unscrew the middle light bulb. What happens? Why?

 

Conclusion:

 

Write a minimum of two paragraphs explaining the differences between series and parallel circuits. BE SURE TO INCLUDE TERMS LIKE POTENTIAL DIFFERENCE, CURRENT, RESISTANCE, AND EXPLAIN USING OHM’S LAW.
