1 of 2
a. A simple circuit is connected to two 1.5 V batteries.
and is connected to an incandescent lightbulb that has a
4.5 filament. Assuming the wires in the circuit have
negligible resistance, how much current is passing
through the entire circuit?
I =
=
A
b. How much power is the lightbulb in this circuit using?
