From the experiment in Table
9, we see that in a parallel circuit,
a) the current is divided among the components, the
component with the higher resistance has the larger
current
b) the current is divided among the components, the
component with the lower resistance has the larger
current
c) the current is the same at all points in the
circuit
d) the current is infinite at all points in the
circuit
1) Next, we will measure the electric current...
