➅
Construct a PARALLEL CIRCUIT, first using combinations of two of the resistors, and then
using all three. Measure and record your values for these circuits.
Parallel

➆ Connect the COMBINATION
CIRCUIT below and measure
the various combinations of
resistance. Do these follow
the rules as you discovered
them before?
