(d) If the voltage supplied by the power source
is 8 V, what would the voltmeters read,
assuming both bulbs are identical.
V1 =
V2 =
(e) Now there are three bulbs. The power supply
has been increased to 12 V. What would be
the reading on the voltmeter if all the bulbs
are identical?
V1 =
Would the voltmeter reading change if the
voltmeter was moved to the top bulb?
(f) Now there are four bulbs. You know that one
of the bulbs is receiving 10 V and all the bulbs
are the same size. What would be the total
voltage supplied to the circuit.
V1 =
2. Write a general statement about the voltage in a parallel circuit. Make sure you discuss
whether or not the number of components alters the voltage for the components.
