CIRCUITS AND MAGNETS
(e) If the voltage across one bulb is 3 V, what is
the total voltage being supplied by the power
supply, assuming the bulbs are identical?
V1 =
(f) The bulbs are the same size. What is the
voltage across the power supply and across
the other bulb?
V1 =
V2 =
(g) The bulbs are the same size. What is the
voltage across the power supply and across
the other bulb?
V1 =
V2 =
(h) The bulbs are different. Solve V1 and then write
a statement about the relative brightness of
the two bulbs.
V1 =
Bulb brightness:

2. Write a general statement about the voltage in a series circuit. Make sure you discuss
whether or not the number of components alters the voltage in the components.
