We have made some simple circuits already. However, everyday
applications already lead to more complicated circuits. We can
understand these just by envisioning where the current is flowing
and where the energy inputs are. Here are some things to think
about and do as we start the section on circuits.
Make a sketch showing how the pipes in a house are arranged, so
that we can be using water two places at once -- Dad is washing the
dog while Mom is filling the fish tank.
Make a sketch showing how the wires in a house are arranged, so
that we can turn on the porch light or the radio or both at once.
Build an actual circuit demonstrating your
solution -- replacing the radio by a buzzer.
