SERIES CIRCUIT
Materials: unipolar wire, one 4.5V battery, three 4.5 V bulbs, one switch, a plywood base. What is it:The series circuit is made up of three bulbs, one after the other (like on a Christmas tree), which are powered by the same source. How it was made:Nail the switch to the plywood base
and connect the unipolar wire to the switch. Connect the bulbs to the
wire; then
fix the wire and bulbs to the plywood base. Connect two alligator clips
to the battery. Note:The exclusion of on bulb cuts out the others too.
