You hook up the circuit shown to the right.
a) Write a voltage equation that states how the voltage drops across the bulbs relate to the voltage gain across the battery . Use this equation along with Ohm's law for each bulb to determine the current flowing through the bulbs (& battery).
b) Determine the voltage across each bulb.
c) In a series circuit with bulbs of different resistances, is a bulb with higher resistance likely to be brighter or dimmer than a bulb with a smaller resistance? Discuss this with your group.
d) Calculate the power dissipated by each light bulb.
e) Calculate the power provided by the battery. Why was this predictable?
f) How does each of the following change if a fourth round bulb is added in series? (you may want to look back over how your answers to (a-c) would change)
Current Voltage drop across each bulb Brightness of each bulb g) What happens if one bulb burns out?
